Terminal Assignment
The terminal blocks are arranged on two sides of the con-
troller: the sensor side and the relay side. The terminals on
the controller consist of multiple sockets for screw terminal
plugs which come together with the controller.
The sensor side (terminals 21-39) consists of terminals
for six analog inputs, one analog output, and three digital
inputs.
The relay side (terminals 1-20) consists of terminals for
power supply (24 Vac/dc), the output for the bipolar
stepper motor, the RS485 interface, and the four relays.
NOTE:
According to VDE guidelines, it is not allowed to mix
low-voltage and high-voltage signals on the relays.
