Main Functions

1. Collect field discrete on‑off status signals from limit switches, interlock contacts, push‑buttons and relay dry contacts.
2. Perform signal filtering, full‑channel optical isolation and digitization; provide high‑precision SOE time‑stamping for contact state change events.
3. Transmit digital status data and SOE event records to main controller via redundant IONet bus.
4. Execute continuous self‑diagnosis for each input channel, detect abnormal input and module hardware faults, and report fault alarm status.
5. LED status indication:   ‑ Green LED：Module power supply normal / RUN status   ‑ Yellow LED：Channel signal / IONet link activity indicator   ‑ Red LED：Module FAIL / channel fault alarm

Installation & Wiring Requirements

1. Cut off I/O pack rack power supply before replacement. Hot‑swap is forbidden. Strict anti‑static protection when handling PCB board.
2. Insert module into designated slot of I/O pack rack, lock module latch to ensure reliable backplane contact.
3. Field discrete signal wiring strictly follow GE Speedtronic Mark VIe wiring manual; signal cables shall be separated from high‑power cables; connect shielding to dedicated ground terminal.
4. Complete protective grounding according to GE system specification.
5. After replacement: verify I/O pack power‑on status, check each channel status reading, perform discrete‑loop commissioning and SOE function test.
6. Replacement note: For TMR triple‑redundant system application, hardware consistency and firmware‑version matching shall be verified; full signal‑loop simulation test mandatory before unit put‑into‑service.
