Troubleshooting Quick Reference
| Symptom | Possible Cause | Relevance to this Part | Quick Check Method | Recommendation |
|---|---|---|---|---|
| No data from channels | No 24VDC loop power | ✅ High | Verify external 24V supply | Check loop power connections |
| Erratic readings | Noise or grounding issue | ✅ High | Check shield grounding | Use shielded cable, single-point ground |
| Open wire alarm | Broken current loop | ✅ High | Measure loop current with multimeter | Repair field wiring |
| Module fault | Configuration mismatch | ✅ Medium | Verify I/O configuration in Proficy | Download correct hardware config |
| Low resolution | Wrong input range selected | ✅ Medium | Check module parameters | Set correct range in software |
Use proper shielded twisted pair wiring for best signal integrity.
Frequently Asked Questions (FAQ)
Is the IC694ALG222 new original? Yes. New Original / New Surplus with full functional verification.
Can I mix voltage and current inputs on the same module? Yes. Each channel can be individually configured for voltage or current in the programming software.
What input ranges are supported? 0-10V, -10 to +10V, 0-20mA, and 4-20mA. Current inputs include open wire detection.
Does it require external power? Yes, 24VDC is needed for current loop transmitters. The module itself draws from the RX3i backplane.
Is the terminal block included? Standard modules ship with the removable terminal block.
Can this module be hot-swapped? In RX3i systems with appropriate configuration, limited hot-swap capability exists, but we recommend powering down for safety.
What warranty is provided? 1-year warranty covering functional performance. Confirm your RX3i rack power budget and software version compatibility.
