Main Functions

1. Converts PLC backplane logic commands into field‑side 24/48 VDC switching signals to drive solenoids, pilot lamps, relay coils and other DC actuators. High‑density 32‑point design optimizes rack slot utilization.
2. Built‑in surge withstand capability handles inrush current of inductive loads. Group‑level over‑current protection prevents module damage under field short‑circuit conditions.
3. Front‑panel LED indicators:   ‑ Individual channel LED: Illuminates when corresponding output channel is ON state.

Installation & Wiring Requirements

1. Cut off full rack power supply before installation or replacement. Hot‑swap is not permitted. Apply ESD protection during module handling.
2. Insert IC697MDL750 into free slot of Series 90‑70 backplane and fasten module latch. Install matching IC697TBB007 terminal‑block assembly.
3. Field wiring comply with manual GFK‑0085H. Connect proper DC power supply to each output‑group common terminals. For inductive loads, install free‑wheel diode across each load coil to suppress voltage spike. Keep output cables separated from high‑voltage power cables. Reliable protective‑ground connection is mandatory.
4. After replacement: Power‑on rack power. Download hardware configuration. Toggle each output bit from PLC software and verify channel LED status and actual field‑load operation. Simulate group over‑current condition to check fault‑reporting behavior.
5. Replacement note: Each output‑group requires independent field power supply; incorrect common‑power wiring will cause entire‑group output failure. Full‑system commissioning test is mandatory before putting into service.
