5.2.5 Digital inputs and outputs
The functions for the digital inputs and outputs shown below are
factory-set. To switch the signal cables, only use relays with low-
current contacts. Relays with gold-plated contacts have proven for
this.
All digital inputs and outputs are PLC compatible and are - when
operated with an external voltage supply (24 V) - isolated from the
rest of the control stage. To connect the voltage supply, use
terminals 39 and 59. If there is no external voltage supply, the
internal 15 V-supply can be used.
External voltage supply (24 V)
Inputs:
Input voltage: 0 to 30 V
LOW signal: 0 to 5 V
HIGH signal: 13 to 30 V
Input current: for 24 V 8 mA per input
Outputs:
Maximum voltage supply: 30 V
Maximum output current: 50 mA per output (external
resistor at least 480
Ω for 24 V,
e.g. relay, part no. 326 005)
