What mounting options are available for the ARC-21W34?

The ARC-21W34 supports various mounting configurations including panel mounting for integration into control cabinets and consoles, VESA mounting patterns for wall or arm installation, and desktop stand options. This flexibility allows the panel PC to be positioned optimally in diverse industrial environments, from dedicated control rooms to production floor operator stations.

What is an Industrial Panel PC?

An Industrial Panel PC is a robust computing device designed for industrial environments, featuring a touchscreen display integrated with a computer. These systems are built to withstand harsh conditions including dust, moisture, temperature extremes, and vibration, while providing reliable operation for factory automation, control systems, and HMI applications.

What makes a Panel PC 'industrial grade'?

Industrial grade Panel PCs feature rugged construction with IP65/IP66 front panel protection, extended temperature operation, shock and vibration resistance, fanless cooling for reliability, wide voltage input tolerance, and long product lifecycles designed for 24/7 operation in challenging environments.

What is the difference between a Panel PC and an HMI?

While both provide operator interface functionality, a Panel PC is a full-featured computer running a standard operating system (Windows, Linux) that can host any software application. An HMI is typically a simpler device with an embedded operating system designed specifically for machine/process control with limited functionality beyond its control software.

What mounting options are available for Panel PCs?

Panel PCs typically offer multiple mounting options including panel mount (cutout installation in cabinets/enclosures), VESA mount (standard bracket mounting to walls or arms), and sometimes desktop stands. Some specialized models may offer additional mounting options for specific industries.

What operating systems are supported on industrial Panel PCs?

Most industrial Panel PCs support Windows 10 IoT Enterprise, Windows 11 Pro, and various Linux distributions like Ubuntu. The specific OS support depends on the hardware configuration, with some models offering pre-installed options or being compatible with multiple operating systems.

What is IP65/IP66 protection and why is it important?

IP65/IP66 protection ratings indicate dust-tight (6) protection and resistance to water jets (5/6). This is essential for industrial Panel PCs that may be exposed to harsh factory environments with dust, splashes, or washdown procedures, ensuring reliable operation and longevity in challenging conditions.

Why are fanless designs important in industrial Panel PCs?

Fanless designs eliminate moving parts that could fail, prevent dust and contaminant ingress through ventilation openings, reduce maintenance requirements, increase reliability in high-vibration environments, and allow sealed enclosures for protection against harsh industrial conditions.

What is PCAP multi-touch technology?

PCAP (Projected Capacitive) multi-touch technology allows multiple simultaneous touch points on the screen, enabling intuitive gestures like pinch-to-zoom. It offers better optical clarity than resistive touchscreens, with a durable glass surface resistant to scratches, though it requires bare finger or special stylus operation.

What is a watchdog timer and why is it important?

A watchdog timer is a hardware-based timer that triggers a system reset if the software becomes unresponsive. This is crucial for industrial systems requiring high reliability and 24/7 operation, as it automatically recovers from software crashes or freezes without human intervention.

What does wide voltage input range mean for Panel PCs?

A wide voltage input range (typically 9-36VDC) allows Panel PCs to operate reliably in industrial environments with fluctuating power conditions. This provides flexibility in power source options and protection against voltage spikes and drops common in factory settings.

What is TPM and why is it included in industrial Panel PCs?

TPM (Trusted Platform Module) is a security chip that provides hardware-based encryption capabilities and secure storage for authentication credentials. In industrial settings, it helps protect sensitive data, secure communication channels, and ensure the integrity of control systems against unauthorized access.

How are Panel PCs typically mounted in industrial environments?

Panel PCs are typically installed using panel mount (where the unit is fitted into a cutout in a control cabinet with mounting clips or screws), VESA mount (attached to arms or wall mounts using standardized mounting patterns), or sometimes with custom mounting solutions for specific applications.

What cutout dimensions are needed for panel mounting?

Cutout dimensions vary by model and screen size. It's essential to refer to the specific Panel PC's installation guide for precise measurements. Most manufacturers provide detailed dimensional drawings showing the exact cutout size and mounting hole positions required.

What environmental conditions should be considered when installing Panel PCs?

Consider operating temperature range, humidity levels, exposure to dust or liquids, vibration/shock conditions, available power supply stability, electromagnetic interference sources, and ambient light conditions that might affect screen visibility when installing Panel PCs.

Do Panel PCs require additional cooling?

Most industrial Panel PCs are designed with fanless cooling systems that dissipate heat through the chassis. While they typically don't require additional cooling, it's important to ensure adequate air circulation around the unit and to avoid installing them in locations that exceed their specified operating temperature range.

What power supply requirements should be considered for Panel PCs?

Consider voltage requirements (typically 9-36VDC), current/power consumption specifications, power supply stability, surge protection needs, and whether battery backup or uninterruptible power supply (UPS) is necessary for critical applications to prevent data loss during power interruptions.

What should I do if the touchscreen becomes unresponsive?

First, try restarting the Panel PC. If the issue persists, check if the touch driver is installed and functioning properly, verify the touchscreen cable connection, ensure the operating environment is within specifications (especially for capacitive screens in high humidity), and check for physical damage to the screen surface.

How can I resolve overheating issues with fanless Panel PCs?

To address overheating: ensure the Panel PC is installed with adequate clearance for passive cooling, check that the ambient temperature is within specified operating range, clean dust buildup on cooling fins/chassis, verify that CPU-intensive applications aren't causing excessive load, and consider adding external cooling to the enclosure if necessary.

What causes Panel PCs to restart unexpectedly?

Unexpected restarts can be caused by unstable power supply, overheating, hardware failures, software issues, or watchdog timer activations due to system hangs. Check power stability, environmental conditions, system logs for error messages, and consider disabling the watchdog timer temporarily for diagnostic purposes.

How can I improve the visibility of the Panel PC screen in bright environments?

To improve visibility in bright environments, adjust the screen brightness to maximum, install an anti-glare shield or hood, position the Panel PC to avoid direct light sources, consider a higher-brightness model (500+ cd/m²) for new installations, or apply an anti-reflective film designed for industrial displays.

What should I do if Windows fails to boot on my Panel PC?

If Windows fails to boot, try booting in Safe Mode, use System Restore to revert to a working state, run startup repair from recovery options, check for hardware issues (particularly storage drives), verify BIOS/UEFI settings are correct, or restore from a system image backup if available.
