Function / Block diagram
The electronic module CU4 Direct Connect operates as
interface between superordinated control (PLC) and is connected
direct by parallel wiring, i.e. every individual signal is on a
separate line. The large input voltage range from 15 to 48VDC
provides for versatile connections. All operating ranges within
the electronic module such as the control of the solenoid valves,
position feedback and LED indication are separated galvanically
and can, thus, be operated with different voltages. Control of the
solenoid valves is effected in energy-saving manner via
pwm-signals.
