OEM SHC CONTROLLER – INSTALLATION INSTRUCTIONS

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.
