Technical Specifications Supply: 24 V DC ±10%; input: 4–20 mA / 0–10 V selectable; output: 0–2.5 A; dither: 50–350 Hz adjustable; ramp time: 0.1–5 s adjustable; operating temp: -40 °C to +85 °C; IP40.
Functional Features Proportional current output; adjustable ramp limiting; zero/span calibration; adjustable dither; short-circuit protection; coil fault detection.
Application Scenarios Smooth valve actuation systems, turbine inlet valves, hydraulic position control, soft-start valve control.
Performance Parameters Current accuracy: ±0.5% FSO; ramp linearity: ±2%; response time: < 18 ms.
Material Composition Sheet metal housing; analog control circuit; power output stage; adjustment potentiometers.
Structural Characteristics DIN rail mount; front accessible adjustment pots; rear terminal block.
Working Principle Conditions the command input with adjustable ramp, then regulates output current proportionally to drive the solenoid valve, with dither to reduce hysteresis.
Installation Requirements Mount on DIN rail; connect control input and valve; adjust ramp time, zero, span and dither.
Usage Notes Set ramp time to avoid hydraulic shock; calibrate zero and span annually; adjust dither for minimum hysteresis.
