System Architecture & Signal Flow
The UMT145B A3 module operates as the central processing unit within the WOODWARD UMT governor chassis. It receives analog and digital input signals from field sensors (speed pickups, pressure transducers, temperature sensors), executes the configured control algorithm in real time, and outputs actuator drive signals to fuel control valves or variable geometry mechanisms. Communication with operator HMI and supervisory SCADA systems is facilitated through the module’s serial or network interface ports as defined by the LR20523 reference drawing.
Signal flow summary:
- Field sensors → Analog/Digital Input conditioning → UMT1 CPU processing → PID/control algorithm execution → Actuator output signals
- Supervisory interface: Serial RS-232/RS-485 or proprietary WOODWARD network protocol
