7 +24V_USER
Power supply for digital inputs. Protect against short circuit and overload. (M24Vdc,
180mA).
8 DI1
Programmable Digital Input 1 (Digital Input 1). Digital inputs are configured in the Input group.
Their status can be displayed in the visualization group. It is powered from terminal 7 or form an
external power 24Vdc supply. If an external power supply is used, the common must be
connected to terminal 29 (GND_USER). Programmable input as PNP and NPN
