6.7.1
PCD3.B100, combined with 2 4 digital I/Os
Application
Economical combined input/output module with:
●
2 inputs 24 V / 8 ms for source operation, electrically connected
●
2 transistor outputs 0.5 A / 5…32 V
DC
, electrically connected, not short circuit
protected, and
●
4 combined inputs/outputs 24 V/8 ms or 0.5 A / 5…32 V
DC
on common I/O
terminals.

*)
Voltage drop:
< 0.3 V at 500 mA for I6 und I7
< 0.7 V at 500 mA for I/O2…I/O5
Total current per module:
3 A steady load
Switch-on delay:
10
µ
s typ.
Switch-off delay:
50
µ
s typ. (100
µ
s max.), (ohmic load 5…500 mA), longer for
inductive load because of protective diode.
*) If the state of a combined output is to be read off, voltage U
ext
must be at least 17 V
DC
,
as the state and the LED are displayed via the input.
