2 Characteristics

This module was developed for general controlling of dynamic systems. The controller structure is designed as
a classic PID compensator with a short cycle time of 1ms.
It is possible to choose from different sensor and command signal types and polarities as 4... 20 mA, 0... 10 V
or 10... 0V. More special input signals can be freely adapted via a mathematical scaling function.
The output signal is available as an active difference signal for the direct connection of valves with integrated
electronics. Alternatively also single ended ones can be used.
The user may choose between two parameter sets by the use of Input S0 (pin 6)
Because of the easy handling a very short training period is guaranteed. A remote control function allows con-
trolling the system without a higher level controller via the serial interface, e.g. for commissioning
The setup via USB is simple and easy to understand. A standard terminal program or our special windows appli-
cation software (WPC-300, download from our homepage) can be used.
Typical applications: dynamic PID compensator for force, pressure and speed control.
