Main Functions

1. Acquire 4‑20 mA / voltage analog signals from pressure, flow and level transmitters.
2. Excitation and sampling for 3‑wire Pt100 / Pt1000 RTD sensors for bearing & lube‑oil temperature measurement.
3. Local DSP performs A‑D conversion, signal filtering, linearization and engineering‑unit scaling, reduce CPU load.
4. HART pass‑through for remote parameter access to HART‑capable field transmitters.
5. Per‑channel diagnosis: open‑wire, short‑circuit, over‑range fault detection, send alarm status to controller.
6. IONet Ethernet backplane communication to exchange measuring data and fault status with main controller.
7. LED status indication:
   • Green LED：Module power‑on and healthy
   • Yellow LED：IONet bus communication active
   • Red LED：Channel fault / communication loss / module hardware fault

Installation & Wiring Requirements

1. Cut off rack power supply before replacement. Hot‑swap is forbidden. Strict anti‑static protection when handling PCB module.
2. Insert module fully into rack slot, lock ejector levers; ensure reliable connection with corresponding terminal base ribbon cable.
3. Field wiring strictly follow GE Mark VIe wiring drawing; separate weak‑signal sensor cables from high‑power cables for noise suppression.
4. Complete protective grounding according to GE Speedtronic system specification.
5. After replacement, verify IONet link status, download module configuration, perform channel calibration; validate measuring values before commissioning.
6. Replacement note: firmware compatibility check and full‑channel function test are mandatory after swap.
