Technical Specifications 24VDC power supply, compatible with LVDT and potentiometer feedback signals. Operating temperature: -40℃ ~ +70℃, built-in excitation source for position sensors.
Functional Features Position sensor excitation, feedback signal sampling, signal linearization, position fault detection, abnormal feedback alarm.
Application Scenarios Gas turbine steam valve control, engine fuel actuator closed-loop control, industrial prime mover governing loops.
Performance Parameters High position sampling precision, low measurement drift, fast feedback response.
Structural Characteristics Rack pluggable PCB module, position channel indicator lights, isolated signal circuit design.
Working Principle The module provides excitation for the position sensor, samples the return feedback signal, calculates the actual actuator opening, and transmits the position value to the main controller for comparison with the target command.
Installation Requirements Route shielded cables for position sensors, keep away from high-current power lines, and fix connectors tightly against vibration.
Usage Notes Match the excitation parameters with the actuator sensor, calibrate zero and full scale after module replacement.
