current controller up to 1A, 3A and 6A
for proportional valves, clutches and brakes
additional PI controller and signal amplifier
narrow snap-on type 22.5mm
The devices are suited to activate proportional control valves, hysteresis clutches, brakes and similar inductive consumer loads. Loads up to 1A (VM6), 3A (VM8) and, respectively, 6A (VM9) can be operated.
There are two modes possible:
Proportional amplifier (control loop) - In this mode, the integrated controller stays disabled and a set value is activated at input . At the maximum set value of 10V, the output current is adjustable from 0...100% using 20-pitch helical trimmer "R1". "R3" shifts the zero point from 0...20%.
Proportional controller to set up control circuits (e.g. for pressure, speed, etc.) - This mode requires enabling of the integrated PI controller via control input  and activation of inputs  and  with set/actual values.
