4.3.4.2 Connection of digital signals
( All digital inputs and outputs are PLC compatible and separated from the
rest of the control module when operated with an external voltage supply
(24 V).
( The diagrams show the function assignments according to the factory
setting.
( For switching the signal cables, only relays with contacts for low-level
switching should be used.
We recommend using relays with gold contacts.
( Voltage supply
- external 24 V to terminals X2/39 and X4/59 or
- internal 15 V to terminal X2/20
Stop!
( Maximum permissible load of the internal 15 V supply : 100 mA.
( For operation with internal voltage: Bridge terminals X2/39 and X3/40
externally.
( Digital inputs unused should be connected!
Inputs:
Input voltage 0 ... + 30 V
LOW level: 0 ... + 5 V
HIGH level: + 13 ... + 30 V
Input current: 24 V:
15 V: 8 mA per input
5 mA per input
Outputs:
Output current: Max. 50 mA per output
(external resistance min. 480
W at 24V,
e. g. relay, order designation EK0005)
The input and output signals are in average read, processed and updated every
4 msec on average.
