It's designed as a general-purpose expandable platform for industrial applications requiring reliable performance and customizable connectivity options.
The SLP-WHG is the base model in the series, offering all the core features without the specialized networking capabilities. While the SLP-WHG-TSN includes TSN (Time-Sensitive Networking) for deterministic Ethernet communication and the SLP-WHG-EtherCAT features dedicated EtherCAT connectivity for motion control, the standard SLP-WHG provides three general-purpose Gigabit LAN ports with both PCIe slots available for custom expansion. This makes it more flexible for applications that require different types of specialized I/O or communication cards.

It also includes a 2.5" internal drive bay. These options allow the system to be tailored to specific industrial requirements through additional communication interfaces, specialized I/O, or custom functionality.
The SLP-WHG is ideal for a wide range of industrial applications requiring reliable computing in challenging environments. Its fanless design, wide temperature operation (-20°C to 50°C), vibration/shock resistance, and flexible expansion capabilities make it suitable for factory automation, machine control, data acquisition, edge computing, IoT gateways, surveillance, digital signage, and transportation systems. The system can be customized with application-specific PCIe cards to address specific requirements in various industrial sectors.
An Expandable Computing System is an industrial-grade computer designed with modular expansion capabilities through slots like PCIe, allowing it to be customized for specific industrial applications. These systems typically feature rugged design elements like fanless cooling, wide temperature operation, and extensive I/O options, while providing flexibility to add specialized functionality through expansion cards for industrial communication protocols, additional I/O, graphics capabilities, or application-specific requirements.
Expandable Computing Systems provide greater flexibility and future-proofing compared to fixed-configuration industrial computers. Their modular design allows customization through expansion cards to meet specific application requirements without replacing the entire system. They can be adapted to changing industrial protocols, upgraded with new capabilities, and scaled to match evolving needs. This modularity extends their useful lifecycle and helps protect the investment as technology and requirements change over time.
Expandable Computing Systems typically support multiple mounting options including wall mounting, DIN rail mounting (common in industrial control cabinets), VESA mounting (for attachment to compatible brackets, arms, or panels), desktop operation (with rubber feet), and in some cases rack mounting with appropriate adapters. This mounting flexibility allows them to be installed in various industrial environments according to space constraints and accessibility requirements.
Fanless industrial computing systems use passive cooling techniques with heat sinks and thermal design to dissipate heat without moving parts. This eliminates a common point of failure, prevents dust ingress, enables sealed enclosures for harsh environments, reduces maintenance, and improves reliability in high-vibration conditions. Fan-cooled systems can typically support higher-performance processors but are more vulnerable to dust contamination, mechanical failure, and require maintenance, making them less suitable for harsh industrial environments.
Most industrial Expandable Computing Systems support Windows 10 IoT Enterprise and various Linux distributions such as Ubuntu, Debian, or specialized real-time operating systems depending on the application requirements. Many industrial applications use Windows due to software compatibility, while Linux is often preferred for embedded applications, IoT gateways, or when real-time performance is critical. The specific OS support depends on the hardware configuration and intended use case.
Wide temperature operation (typically -20°C to 60°C or similar range) ensures reliable functioning in non-climate-controlled industrial environments like factory floors, outdoor installations, vehicles, and remote locations. This capability is achieved through careful component selection, thermal design, and elimination of moving parts like fans. Systems with wide temperature ranges can be deployed in harsh conditions without requiring expensive climate control systems, reducing installation and operating costs while improving reliability.
Wide voltage input (typically 9-36VDC or similar range) allows industrial computers to operate reliably with varying power sources common in industrial environments. This feature protects against voltage fluctuations, accommodates different international power standards, enables direct connection to vehicle electrical systems (12V/24V), and provides resilience against power quality issues. The wide input range also eliminates the need for precise voltage regulation, simplifying installation and improving reliability in challenging power environments.
TPM (Trusted Platform Module) 2.0 is a specialized security chip that provides hardware-based encryption capabilities, secure storage for authentication credentials, and system integrity verification. In industrial systems, TPM helps protect sensitive data, secure communication channels, prevent unauthorized access or tampering, and ensure the integrity of control systems. As industrial systems become more connected, TPM provides essential security features to protect against cyber threats targeting critical infrastructure and manufacturing systems.
Vibration and shock resistance are critical for industrial computing systems operating in environments with mechanical disturbances from machinery, vehicles, or handling. Systems are tested to standards like IEC 60068-2-64 (vibration) and IEC 60068-2-27 (shock) to ensure they can withstand these forces without component failure or connection issues. This resilience is achieved through solid-state storage, elimination of moving parts, reinforced component mounting, specialized chassis design, and industrial-grade components, ensuring reliable operation in mechanically challenging environments.
Multiple display outputs (such as HDMI, DisplayPort, or VGA) on industrial computing systems enable simultaneous connection to various monitoring and control interfaces. This capability supports control room setups with multiple screens showing different aspects of operations, operator interfaces combined with process visualization displays, redundant displays for critical applications, digital signage applications requiring multiple screens, and flexible configuration options for different industrial visualization needs without requiring additional graphics adapters.
A watchdog timer is a hardware-based timer that triggers a system reset if the software becomes unresponsive. This critical reliability feature ensures that industrial systems recover automatically from software freezes, crashes, or other unexpected conditions without human intervention. For 24/7 industrial applications where downtime is costly and systems may be remotely located, the watchdog timer provides an essential fail-safe mechanism that helps maintain continuous operation even when software issues occur.
When installing expandable computing systems in industrial environments, consider proper thermal management (ensuring adequate airflow around the unit), environmental protection (enclosures appropriate for dust/moisture levels), power quality (stable power source, possibly with UPS), EMI/RFI isolation (distance from high-interference sources), physical security, accessibility for maintenance, proper grounding, cable management (strain relief and protection), and compliance with local regulations and industry standards. Proper planning of these factors ensures reliable operation and longevity of the system.
While fanless systems don't require active cooling, they still need proper thermal management. Ensure adequate clearance around all sides of the unit (typically at least 5-10cm), avoid enclosing in sealed cabinets without ventilation, mount vertically if possible for better convection cooling, keep away from other heat-generating equipment, consider ambient temperature fluctuations, use the mounting method recommended by the manufacturer (often including heat-dissipating brackets), and for high-temperature environments, consider additional passive heat sinks or cabinet cooling if available.
For expandable computing systems, select a power supply with sufficient wattage for the base system plus all expansion cards (with 20-30% headroom for future expansion), ensure voltage matching the system's input range, consider efficiency ratings for power consumption, evaluate connector compatibility, implement surge protection for industrial environments with electrical noise, consider redundant power options for critical applications, use proper wire gauge for current requirements, and potentially include an uninterruptible power supply (UPS) for protection against power outages.
When setting up networking for expandable computing systems, consider network security (VLANs, firewalls, access controls), redundancy options for critical applications, cable quality and shielding appropriate for the industrial environment, proper grounding to prevent ground loops, cable length limitations, network segregation between IT and OT (operational technology) if applicable, bandwidth requirements for the application, latency sensitivities, management of MAC/IP addresses, and compliance with any industry-specific networking standards or protocols.
When installing expansion cards, first ensure system power is completely off and disconnected, follow ESD (electrostatic discharge) precautions including wrist straps, carefully follow the manufacturer's instructions for chassis access, identify the correct expansion slot type (PCIe x1, x4, etc.), align the card carefully with the slot, apply even pressure until fully seated, secure with mounting screws if provided, connect any additional power cables if required, and avoid forcing connections. After installation, ensure proper driver installation and check for device recognition in the operating system.
If the system fails to power on, check that the power supply is properly connected and functioning (verify with a multimeter if possible), confirm the power cable is securely connected at both ends, ensure the input voltage matches the system's requirements, check for tripped circuit breakers or blown fuses, verify the power button functionality, check internal power connections if accessible, inspect for any visible damage to power components, and try an alternative known-good power supply if available. If using an ATX power mode, check if the system requires a specific power-on sequence.
For expansion card connectivity issues, verify the card is properly seated in its slot, check if appropriate drivers are installed and updated, confirm BIOS/UEFI settings have the slot enabled, inspect for physical damage to the card or slot, try the card in an alternative slot if available, test with a known-working card to verify slot functionality, check for resource conflicts in Device Manager (Windows) or system logs (Linux), ensure sufficient power for the card, and consider BIOS updates that might address compatibility issues. For specialized cards, consult the card manufacturer's troubleshooting guides.
For overheating issues, check that the system has adequate clearance for passive cooling (at least 5-10cm on all sides), clean any dust buildup on heat sinks or chassis using compressed air (when powered off), verify the ambient temperature is within the system's specified operating range, ensure the system is mounted properly for optimal heat dissipation (often vertically), check if thermal paste needs replacement on CPU/GPU if accessible, monitor CPU usage for runaway processes causing excessive load, and consider adding auxiliary passive cooling or relocating the system to a cooler environment if persistent.
For network issues, check physical connections (cables and ports for damage), verify link lights are active, test with alternative known-good cables, check IP configuration (static vs DHCP), ping the gateway and other network devices, examine firewall settings that might block connectivity, verify network services are running, check for IP address conflicts, inspect routing tables, try disabling and re-enabling the network interface, update network drivers, check for MAC address filtering on the network, and use diagnostic tools like ipconfig/ifconfig, traceroute, and network monitoring utilities to identify where communication fails.
For boot failures, observe any error messages or beep codes during startup, verify boot device priority in BIOS/UEFI, check if the boot drive is detected in BIOS, try booting in safe mode, use recovery tools from the OS installation media, check for corrupt boot files, verify storage connections are secure, run hardware diagnostics if available, check for BIOS/UEFI updates that might resolve compatibility issues, reset BIOS to defaults if appropriate, and examine the system event log for clues. For systems with removable storage, try booting from a known-good OS installation on external media.
