Main Functions

1. Provide configurable loop power for two‑wire field transmitters, collect 4‑20 mA and millivolt safety‑related analog signals.
2. Complete signal conditioning, filtering and high‑precision A‑D conversion, convert raw analog signals into engineering‑unit digital values.
3. Transmit critical process‑variable data to Mark VIe main controller via dual redundant IONet bus for turbine safety protection logic calculation.
4. Channel‑level fault diagnosis: detect transmitter open‑circuit, short‑circuit and signal over‑range; mark faulty channel without affecting other measurement channels.
5. On‑board self‑diagnosis: detect watchdog timeout, internal reference drift, dual‑IONet 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：Analog‑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, engage locking mechanism; ensure backplane connection is reliable.
3. Field transmitter wiring strictly follow GE Speedtronic Mark VIe wiring manual; analog signal cables adopt 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 reading, simulate transmitter open‑short fault condition before commissioning.
6. Replacement note: For TMR triple‑redundant system application, hardware consistency of related redundant packs shall be verified; full analog‑loop simulation test mandatory after unit put‑into‑service.
