How to Connect a Remote Power Switch to an Industrial PC

1. The Accessibility Challenge in Industrial Environments

In many factory setups, Industrial Box PCs are installed inside sealed control cabinets or NEMA enclosures to protect them from dust and heat. While this keeps the hardware safe, it makes the physical power button impossible to reach.

If a system needs a manual reboot, opening a locked cabinet is time-consuming and can be a safety hazard. This is especially useful for fanless industrial computers installed in dust-proof cabinets. A Remote Power Switch solves this by moving the power control to a more convenient location.

2. What is a Remote Power Switch Terminal?

On the back of a professional Industrial PC (IPC), you will usually find a small green connector. This is a Phoenix Terminal Block.

This terminal acts as an external bridge for the motherboard's power headers. Instead of reaching inside the case, you can connect two wires to this block to "relocate" the power button functionality anywhere on your machine.

3. Why Professional Integrators Use Physical Terminals

There are several ways to start a computer, but the physical terminal is the industry favorite for a few reasons:

• Hardware-Level Reliability: It uses a Dry Contact signal. This means it works even if the operating system is frozen or the network is down.
• Secure Connection: The screw-lock design of the Phoenix Connector ensures that wires stay connected, even in environments with heavy vibration.
• Simplicity: It does not require complex BIOS or network configurations like Wake-on-LAN (WoL).

4. Technical Setup: Connecting an External Button

Setting up a remote switch is a "no-soldering" task. It is designed for quick field installation.

Components Needed:

• Momentary Push Button: Use a "normally open" (NO) industrial button that completes the circuit only when pressed.
• 22-24 AWG Wire: Standard copper wiring is sufficient for most distances.
• Flathead Screwdriver: To secure the terminal screws.

The Installation Steps:

Step 1: Strip about 5mm of insulation from your wires.

Step 2: Insert the wires into the PWR and GND pins on the terminal block.

Note: This connection is polarity independent, meaning it doesn't matter which wire goes into which hole.

Step 3: Tighten the screws until the wires are firmly held.

Step 4: Mount your button on the outside of your cabinet and connect the other end of the wires.
