Diagnostics & Indicators

LEDs: PASS, FAULT, ACTIVE, LOAD, PWR1, PWR2 (module status)

Monitoring: Per‑channel current readback; open/short‑circuit detection; overrange/underrange alarms

Protection: Overvoltage (+36VDC continuous), overcurrent, short‑circuit, overtemperature

Fail‑Safe: Configurable hold‑last‑value or preset safe‑value on fault

Core Functions

Bipolar High‑Current Drive (−60…+60mA)

Delivers bidirectional, high‑current output for servo valves, hydraulic actuators, DC motors (direction + speed control) and other specialized field devices needing positive/negative drive.

TMR SIL3 Safety Architecture

Triple‑modular redundancy with 2oo3 voting eliminates single‑point failures; meets SIL3 for safety‑critical motion/positioning loops.

13‑Bit Precision & Per‑Channel Diagnostics

13‑bit resolution ensures accurate positioning; real‑time current readback and fault detection validate output integrity.

Hot‑Swap & Redundancy Compatibility

Online replacement without shutdown; compatible with redundant I/O architectures for maximum availability.

Applications

Oil & Gas: ESD‑critical servo valves, hydraulic actuator control, subsea valve positioning

Power Generation: Steam turbine hydraulic governors, boiler feedwater valve servos, generator excitation control

Chemical/Refining: Reactor agitator DC motor control, precision distillation column valve positioning

Industrial Motion: Bidirectional actuators, servo systems, high‑force positioning requiring ±60mA drive
