5.2.3. Digital inputs and outputs (DC2115)
The digital outputs are positive switching 24 V outputs with an output current of max. 500 mA. They have a
common reference potential (GND) with the supply voltage.
NOTE
Damage to the inputs or to the device!
Voltages over ±32 V can damage the inputs or the device.
No voltage in excess of ±32 V may be present at the inputs.
The digital inputs are type 1 or 3 (IEC 61131-2) positive switching inputs of type 1 or 3 (IEC 61131-2). They are
designed for nominal input voltages of 24 V. The input signals are transmitted internally on a cyclical basis
for process data processing. An open input is interpreted as static 0. The inputs also have a common refer-
ence potential (GND).
The following counterparts have been tested with the S2C-SMT 3.5 (Weidmüller) connector and are ap-
proved for use with the device:
B2CF 3.50/12/180F
