Product Introduction
The GE IC670CHS002 is a 2-tier box-style I/O terminal block for the Field Control series. It serves as the wiring base that mounts up to two I/O modules while providing the backplane connection and screw terminals for field wiring in GE Genius bus systems.
This terminal block is a direct replacement part used heavily in distributed I/O setups on machines and processes where vibration resistance and secure wiring matter. It handles up to 10A per terminal and accepts a wide range of wire sizes, making it a reliable choice for both new installations and field replacements.

Troubleshooting Quick Reference
| Symptom | Possible Cause | Relevance to this Part | Quick Check Method | Recommendation |
|---|---|---|---|---|
| No power to modules | Loose or broken terminal connections | ✅ High | Measure 24V DC at module power terminals on the block | Tighten terminals to spec; inspect for broken wires |
| Intermittent I/O signals | Poor wire termination or vibration | ✅ High | Check torque on all box terminals; tug test wires | Re-terminate wires; replace block if terminals are stripped |
| Module will not seat properly | Damaged backplane connectors on base | ✅ Medium | Visual inspection of gold contacts | Clean contacts or replace terminal block |
| High resistance on inputs | Corrosion on terminals | ✅ Medium | Measure continuity from wire to module pin | Clean or replace affected terminals |
| Bus communication errors | Faulty backplane link through base | ❌ Low | Swap with known good base | Replace IC670CHS002 if errors follow the base |
Contact technical support with photos of the installation, wiring, and any diagnostic LEDs or error codes from the Bus Interface Unit if issues persist.
Frequently Asked Questions (FAQ)
Is the IC670CHS002 new original stock or refurbished? This unit is New Original / New Surplus. It comes from factory-sealed or OEM excess inventory with full traceability. We perform full inbound inspection and functional checks before shipping.
Can I use this terminal block with any Field Control I/O modules? Yes. It accepts any two compatible Field Control I/O modules. Always confirm module catalog numbers against the GE Field Control manual for pin compatibility.
Does this support hot-swapping of modules? No. You must remove power to the station before swapping modules on this terminal block. Hot-swapping risks damage to the backplane or modules.
What wire size works best? AWG 14 down to AWG 22 copper wire. Use two AWG 18 if needed. Follow the 4.5 in/lbs torque recommendation for reliable connections under vibration.
Is this a direct replacement for older terminal blocks? Yes. The IC670CHS002 is the standard 2-tier box terminal block used across Field Control installations. Match your existing wiring diagram and module types.
What is the warranty on this part? We provide a 1-year warranty on functional operation. Units are tested on actual Field Control hardware before shipment.
How do I verify firmware or configuration on the connected modules? The terminal block itself has no firmware. Configuration lives in the connected I/O modules and Bus Interface Unit. Use Proficy Machine Edition or the Hand-Held Monitor to check diagnostics.
