Technical Specifications Supply voltage: 18–32 V DC (24 V DC nominal); command input: 4–20 mA from governor; actuator output: 0–2 A proportional current; 2 digital enable inputs; current feedback output: 4–20 mA; operating temperature: -40 °C to +85 °C; protections: output short-circuit, overcurrent, over-temperature; enclosure: IP20.
Functional Features Proportional current drive for electric actuators; current feedback for closed-loop control; enable/disable control input; output short-circuit and overcurrent protection; actuator fault detection; smooth output response.
Application Scenarios Electric fuel actuator drive for engine governors, proportional valve control, industrial actuator power amplification, governor system actuator interface.
Performance Parameters Output current accuracy: ±1% full scale; response time: < 10 ms; output ripple: < 10 mA peak; current sense accuracy: ±0.5%.
Material Composition Industrial plastic housing, power MOSFET output stage, precision current sense resistor, control circuit board, screw terminal connectors.
Structural Characteristics Compact rack plug-in form factor; front status and fault LEDs; rear terminal block for input, output and power wiring; standard mounting footprint.
Working Principle The module receives the 4–20 mA command signal from the digital governor, converts it to a proportional output current to drive the electric actuator, and provides a proportional current feedback signal back to the governor for closed-loop current control.
