Description
The MDR-137-P is a pressure control module with an integrated power amplifier and analogue A sensor interface used to control the pressure (and, optionally, the speed) of a hydraulic system. It incorporates a PID controller.
Key features anad characteristics:
- Control of pressure-reducing and pressure-regulating valves
- Compact design
- Digitally reproducible setting
- Universal PID controller
- Free configuration of ramps, MIN and MAX, dither (frequency, amplitude) and PWM frequency
- Current range (configurable via software) up to 2.6 A
- Application-oriented parameterisation
- Fault diagnosis and advanced functional testing
- Configuration via USB using the WPC-300 software
- Regulated output current, independent of supply voltage and magnetic resistance
- Monitoring of the output stage for cable breaks and overcurrent (short circuit), with automatic shutdown in the event of a fault
How it works:
The module controls pressure valves. The setpoint and actual value are transmitted via a 0–10 V signal (optional 4–20 mA with cable break monitoring). It features a ramp function and a PID controller. The digital input signal ENABLE initialises the application, clears Error messages activate the output stage and the READY signal. The START signal triggers the Control function activated. Control is carried out using a PID controller specifically optimised for these applications.
Applications:
- Pressure control using pressure valves and servo pumps
- Speed control using analogue speed sensors (tachometer)
- Pressure control systems on constant-flow pumps
- Remotely adjustable control pumps
- Power and torque control for cylinders and motors
