The power supply is connected
- for 230 V/115 V AC by a three-pin plug
- for 24 V UC by a special two-pin plug.
On the standard controller the field lines (signal cables) are connected to three functionally
combined plug-in screw-type terminals.
The options modules for analog inputs and digital inputs- and outputs have their own ter-
minals which are also designed as plug-in screw-type terminals.
The interface module is connected by its own plug.
