TRICONEX 3807 Analog Output Module

Product Description

TRICONEX 3807 is a 4-channel bipolar analog output module for the Tricon TMR triple modular redundant system, with an output range of -60mA ~ +60mA. It adopts DC-coupled common return design, dedicated for forward/reverse regulation of servo coils, electro-hydraulic servo valves and actuators. The module is equipped with dual current loopback diagnostic circuits, supporting self-calibration, open/short circuit detection and rack hot-swap, used together with matching termination panel. It is mainly deployed in turbine speed control loops and not intended for SIL safety interlock outputs.
