Main Functions

1. High‑precision analog‑to‑digital conversion for process sensors (pressure, temperature, flow transmitters 4‑20 mA / ±10 V signals) in Series 90‑70 control system. Each channel supports independent engineering‑unit scaling.
2. Dedicated expander interface connects ALG440 / ALG441 expansion modules to greatly increase analog input channel quantity without consuming additional PLC rack slots.
3. Per‑channel fault diagnosis: open‑loop detection, over‑range / under‑range alarm, convenient for field sensor fault troubleshooting.
4. Front‑panel LED indicators:   ‑ Green OK: Module hardware self‑test pass   ‑ Red FAULT: Module hardware fault or configuration error   ‑ CH 1‑8: Channel status / over‑range indication

Installation & Wiring Requirements

1. Cut off full rack power supply before installation or replacement. Hot‑swap is not supported. Apply ESD protection during module handling.
2. Insert IC697ALG230 into free slot of Series 90‑70 backplane rack and lock module latch. If expanders are used, connect ribbon cable between ALG230 and expander modules.
3. Field analog wiring comply with manual GFK‑0385G. Use shielded twisted‑pair cable for analog signals; separate analog wiring from high‑voltage power cables. Reliable protective‑ground connection is mandatory.
4. After replacement: Power‑on rack power, check front‑panel LED status. Download hardware configuration, configure channel signal type, scaling and filter parameters. Apply simulated analog signal to verify each channel conversion value and fault‑diagnosis function.
5. Replacement note: Verify total rack backplane power budget. Check ribbon‑cable connection if expander modules are present. Full‑system commissioning test is mandatory before putting into service.
