Digital inputs/outputs
Relays
RS232/RS485 interface
Version Terminals and connection symbol Connection element.terminal /
assignment
Digital input DC 0/24 V
or
digital output DC 0/24 V
(individually switchable),
auxiliary voltage supply DC 24 V
Note regarding the digital option:
Auxiliary voltage supply and digital outputs to-
gether deliver max. 100 mA (at 24 V).
Example: potential-free contact on digital input/
output 1 (as input) and +24 V (auxiliary voltage)
