Mechanical Data

‑ Weight：approx 0.43 kg ‑ Dimension：Series‑90‑30 standard single‑slot module form‑factor ‑ Handling note：ESD‑sensitive precision analog circuit, anti‑static wrist‑strap mandatory during handling ‑ Terminal tightening torque：0.6‑1.0 N·m

Main Functions

1. Collect process current signals from field 2‑wire /4‑wire pressure, flow, level and temperature transmitters.
2. Software configurable per‑channel range; Enhanced mode detects broken transmitter wiring for field troubleshooting.
3. Convert analog current signals to 12‑bit digital data, communicate with Series‑90‑30 CPU via backplane bus.
4. Channel‑level fault diagnostics: over‑range, under‑range and open‑loop fault, upload alarm status to PLC CPU.
5. LED status indication:   ‑ Green OK：Module power‑on and self‑test pass

Installation & Wiring Requirements

1. Cut off Series‑90‑30 PLC rack power and external 24VDC field‑loop power before replacement. Hot‑swap is forbidden. Strict anti‑static protection when handling module.
2. Insert IC693ALG223D fully into PLC backplane slot and lock latch.
3. Field instrument wiring strictly follow GE Series‑90‑30 hardware manual; adopt shielded twisted‑pair instrument cable; separate analog signal cables from high‑power cables, connect shielding to dedicated protective ground terminal.
4. Complete protective grounding according to GE system specification.
5. After replacement: power‑on PLC, verify OK LED status, download module channel configuration, perform full‑channel signal test and open‑wire fault‑simulation test.
6. Replacement note: Verify CPU firmware compatibility; full analog‑loop simulation test mandatory before unit put‑into‑service.
