Description
The MDR-133-U or MDR-133-P is a pressure control module designed to regulate pressures and forces in hydraulic systems. The control structure is designed for pressure control loops with typical Optimised with pressure valves and easy to operate. It features a PID controller for precise Control.
Key features and characteristics:
- Analoge Drucksollwerte und Druckistwerte
- Special pressure control concept for pressure-limiting and pressure-reducing valves
- Optimised controller for pressure control loops
- Simple controller optimisation
- Ramps for pressurisation and depressurisation
- Simple and application-oriented parameterisation
- Standard USB Plug
- Fault diagnosis and advanced functional testing
- Simplified parameterisation from WPC-300 software version 3 onwards
- Optionally available with an integrated power amplifier (P version)
- Programmable output (0–10 V or 4–20 mA) and analogue sensor interface (MDR-133-U)
- Additional power amplifier up to 2.6 A (MDR-133-P)
How it works:
The module operates using a bypass control system, in which the setpoint signal is fed directly to the control output
(pressure valve). The controller therefore only compensates for linearity errors. An enable signal activates the controller’s output, which can then be controlled by the setpoint. Operational readiness is signalled via a ‘Ready’ signal. The controller is activated by the ‘Start’ signal, and the current actual value is read in. The output signal is generated on the basis of the control deviation and the controller parameters.
Applications:
- Pressure control using pressure relief valves or pressure-reducing valves
- Pressure control systems on constant-flow pumps or remotely adjustable control pumps
- Force and torque control systems for cylinders and motors
