Main Functions

1. Screw‑terminal field termination for field discrete dry‑contact / wet‑contact signals: breaker status, valve limit position, auxiliary equipment running feedback, pressure‑switch interlock contacts.
2. Optical isolation between plant field wiring and internal control logic, suppress ground‑loop noise and industrial surge interference.
3. Convert contact open‑close status into digital logic signals, transmit to PAIC I/O pack via ribbon‑cable link for turbine logic processing.
4. On‑board channel fault diagnosis: detect field‑loop open‑circuit fault, report fault status to main controller.
5. On‑board self‑diagnosis: detect terminal‑board auxiliary power loss and ribbon‑cable link failure.
6. LED status indication:
   • Green LED：Terminal‑board auxiliary power normal
   • Yellow LED：Ribbon‑cable link communication active
   • Red LED：Field‑channel fault / link communication loss alarm

Installation & Wiring Requirements

1. Cut off rack power supply before replacement. Hot‑swap is forbidden. Strict anti‑static protection when handling PCB board.
2. Secure DIN‑rail mounting bracket firmly; ensure 37‑pin IDC ribbon‑cable connector fully locked without loose contact.
3. Restore on‑board jumper setting (dry‑contact / wet‑contact voltage mode) strictly consistent with original configuration before field wiring.
4. Field contact‑signal wiring strictly follow GE Speedtronic wiring manual; discrete signal cables adopt shielded twisted‑pair, separate from high‑power cables; connect shielding to dedicated ground terminal.
5. Complete protective grounding according to GE Speedtronic system specification.
6. After replacement: verify ribbon‑cable link status, test each channel open‑close response, validate interlock‑signal logic before commissioning.
7. Replacement note: This hardware is simplex‑only, cannot apply for TMR triple‑redundant safety trip loops; full‑channel discrete‑input function test mandatory after swap.
