Main Functions

1. Converts field 24 VDC discrete sensor and contact signals into backplane logic data for Series 90‑70 CPU. High‑density 32‑point design optimizes rack slot utilization.
2. Dual‑logic wiring support: positive‑logic (PNP‑sensor sinking input) and negative‑logic (NPN‑sensor sourcing input) adaptable to different field device types.
3. Software‑configurable input filter suppresses electrical noise and contact bounce; electronic short‑circuit protection improves field‑fault survivability.
4. Front‑panel LED indicators:   ‑ Individual channel LED: Illuminates when corresponding input 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 IC697MDL653 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‑0379F. Connect group‑common terminals correctly according to selected positive‑/negative‑logic mode. Use shielded cables for noisy field signals. Reliable protective‑ground connection is mandatory.
4. After replacement: Power‑on rack power. Download hardware configuration and set input filter time parameter. Toggle each field input and verify corresponding channel LED and PLC register status. Simulate short‑circuit condition to check module protective behavior.
5. Replacement note: Confirm each group‑common terminal is properly wired; missing common connection will cause entire group input failure. Full‑system commissioning test is mandatory before putting into service.
