Main Functions

1. Provide stable excitation source for field bridge‑type sensors, receive differential analog signals from strain‑gauges, excitation feedback transducers and position‑related bridge instruments.
2. Complete signal conditioning, filtering and high‑precision A‑D conversion, convert bridge differential signals into engineering‑unit digital values.
3. Acquire multi‑channel discrete contact status signals for auxiliary‑equipment interlock, permissive and fault‑feedback logic.
4. Transmit processed analog and discrete data to main Mark VIe controller via IONet bus.
5. On‑board channel‑level self‑diagnosis: detect bridge‑sensor open‑circuit/short‑circuit, signal over‑range, discrete‑input abnormality, watchdog timeout and communication link failure; upload fault alarm to turbine main controller.
6. LED status indication:
   • Green LED：Module power supply normal / RUN status
   • Yellow LED：IONet bus communication active
   • Red LED：I/O‑channel fault / module FAIL alarm

Installation & Wiring Requirements

1. Cut off rack power supply before replacement. Hot‑swap is forbidden for non‑hot‑swap configuration; strictly follow Mark VIe maintenance procedure for hot‑swap version. Strict anti‑static protection when handling PCB board.
2. Insert I/O pack into designated rack slot, secure locking mechanism; ensure backplane bus connection is reliable.
3. Field sensor wiring strictly follow GE Speedtronic Mark VIe wiring manual; bridge‑signal cables adopt high‑quality shielded twisted‑pair, strictly separated from high‑power cables; connect shielding to dedicated ground terminal.
4. Complete protective grounding according to GE system specification.
5. After replacement: verify module power‑on status, check each‑channel analog and discrete reading, simulate sensor fault condition before commissioning.
6. Replacement note: For TMR triple‑redundant system application, hardware consistency of related redundant packs shall be verified; full signal‑loop simulation test mandatory before unit put‑into‑service.
