5.3.3. Digital inputs of the ECC DIO 16/16
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.
Depending on the version of the device, the digital inputs are positive or negative switching inputs of type 1
(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 always interpreted in the
programming system as logical 0 (LOW) (level: 0 V for P, +24 V for N). The inputs also have a common
reference potential (GND).
The following counterparts have been tested with the SC-SMT 3.81 (Weidmüller) plug-in connector and are
approved for use with the device:
Weidmüller BCZ 3.81/16/180 (F, LH)
Weidmüller BCF 3.81/16/180 (F, LH)
