Main Functions

1. Collect 4‑20 mA /0‑20 mA current signals from field pressure, flow, level and temperature transmitters.
2. Perform analog‑to‑digital conversion, transmit digital process values to BIU over local backplane, then upload to Genius‑bus master controller.
3. Built‑in channel‑level fault diagnosis: open‑loop, over‑range detection, convenient for field‑side troubleshooting.
4. LED status indication:   ‑ Green OK：Module power‑on and self‑test pass

Installation & Wiring Requirements

1. Cut off BIU rack power and field 24VDC loop power before replacement. Hot‑swap is forbidden. Strict anti‑static protection when handling module.
2. Insert IC670ALG230 fully into Field‑Control BIU base slot and lock firmly.
3. Analog‑loop wiring strictly follow GE Field‑Control hardware manual GFK‑0893G; use shielded twisted‑pair instrument cable; separate analog signal cables from high‑power cables, connect shielding to dedicated protective ground terminalQualitrol.
4. Complete protective grounding according to GE system specification.
5. After replacement: power‑on, verify OK LED status, download module channel configuration, perform full‑channel signal test and fault‑simulation test.
6. Replacement note: Verify BIU hardware and firmware compatibility; full analog‑loop simulation test mandatory before unit put‑into‑service.
