Core Functions

1. Multi‑channel isolated analog output (4‑20 mA) for proportional control of fuel valves, steam valves and electro‑hydraulic actuators.

2. High‑precision digital speed signal acquisition via magnetic pickup (MPU), supporting real‑time speed monitoring and overspeed protection logic.

3. Seamless backplane bus communication with MicroNet TMR / Atlas III+ main controllers, low‑latency control signal transmission.

4. Built‑in surge protection, short‑circuit protection and open‑circuit detection for field wiring faults.

5. Conformal‑coated PCB, strong anti‑interference, anti‑vibration and high‑temperature resistance for power‑plant and offshore oil‑gas environments.
