Key Features & Benefits

• This block delivers built-in cold junction compensation using integrated thermistors.
• It isolates temperature readings from process heat and electronic interference.
• The IC670CHS004 supports connection for two separate thermocouple sensors.
• You must ensure a solid chassis ground connection for accurate compensation.
• It works exclusively with dedicated GE Fanuc Field Control thermocouple input modules.
• A proper crimp tool (like AMP Pro-Crimper II 90546-1) guarantees reliable wire terminations.

Installation & Compatibility Guide

• Connect your field thermocouple wires directly to this terminal block's screw terminals.
• This base then links to the I/O module via proprietary connectors and wiring.
• It compensates for temperature variations at the connection point (cold junction).
• Only qualified technicians should perform the installation and grounding procedures.
• Always verify compatibility with your specific GE Fanuc thermocouple input modules.

Frequently Asked Questions (FAQ)

• Q: What is the main purpose of the IC670CHS004?
  A: Its primary role is to provide a connection point and critical cold junction compensation for thermocouple signals, ensuring temperature reading accuracy.
• Q: How many thermocouples can one block support?
  A: A single IC670CHS004 terminal block can interface with two independent thermocouple sensors.
• Q: Why is grounding so important for this unit?
  A: A tight chassis ground is essential for the internal compensation circuit to function correctly and reject electrical noise.
• Q: Is it hot-swappable?
  A: Yes, the design supports hot-swapping, allowing you to replace or maintain it without shutting down the entire system.
• Q: What is the product condition and shipping time?
  A: We supply the IC670CHS004 brand new and in original packaging. We ship from available stock, typically within 5 business days via carriers like DHL, FedEx, or UPS. We offer a 30-day return policy for unused items.
