IC693ALG392
4. Product Introduction
The GE IC693ALG392C delivers 8-channel analog output control for GE Series 90-30 PLC systems, supporting 4-20mA, 0-20mA, 0-10V, and -10-10V signals. Its 12-bit resolution ensures precision in valve positioning, VFD speed regulation, and sensor interfacing.
Key advantages include:
-
1500V RMS isolation to mitigate EMI from VFDs and motor drives.
-
Software-selectable ranges eliminate hardware rewiring.
-
Compact design reduces panel footprint by 60% compared to multi-module setups.
5. Firmware/Software Versions & Upgrade Notes
-
Recommended Firmware: v3.0.1 (last stable Series 90-30 release; fixes v2.9.x comms bugs).
-
Compatibility:
-
PLC Compatibility: Series 90-30 CPUs (e.g., IC693CPU331). Configurable via Logicmaster 20/30 or Proficy Machine Edition.
-
Communication: Native backplane protocol; no Modbus RTU support.
-
-
Upgrade Risks:
-
v3.0.1 requires PLC cold restart (no hot-swap).
-
Downgrading to v2.9.x may cause output drift—backup program first.

6. Frequently Asked Questions (FAQ)
1. Can I hot-swap the IC693ALG392C?
No. Hot-swapping risks backplane shorts. Power down the rack, verify 5V/24V stability, then replace. The module’s 110mA backplane draw demands stable power—test with a multimeter first.
2. Is this module obsolete?
Yes. OEM discontinued it in 2022. Use IC693ALG393 (identical form factor, enhanced ESD protection) or migrate to RX3i IC694ALG392A (16-bit resolution).
3. Will programming memory reset when swapping CPUs?
Only if the CPU lacks battery backup. Export the PLC program (via Proficy) before swaps. The module’s firmware is stored locally—no impact on CPU memory.
4. What’s the warranty for “New Surplus” units?
12 months, covering manufacturing defects. We perform:
-
Incoming traceability checks (OEM serial verification).
-
24h load test (110mA continuous output).
-
Megger insulation test (>10MΩ).
5. Why is this cheaper than OEM but pricier than refurbished?
This is New Surplus: unused stock with full QC (anti-static packaging, calibration backups). Refurbished units often have degraded capacitors or untested isolation—risking unplanned downtime.
6. How to verify output accuracy?
Use a loop calibrator to inject a 4-20mA signal. Monitor
%AQregisters in Proficy—values should match input. If discrepancies occur, check:-
Output range configuration (software-selectable).
-
Field wiring (shielded STP cable, ground to “GND” terminal).
7. What ESD precautions apply?
Use grounded wrist straps and static-dissipative mats. The module’s CMOS outputs are sensitive to >50V ESD—common in dry climates. Store in anti-static bags when not installed.
