5.2.5 PCD3.B100, 2 + 4 digital inputs /outputs
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 VDC, electrically connected,
not short circuit proof and
●
4 combined inputs /outputs 24 V/ 8 ms or 0.5 A/5...32 VDC
on common I/O terminals
Technical data on inputs

high-range:
-30...+5 V
+15...+32 V
4 inputs I/O2 to I/O5
low-range:
high-range:
-0.5...+5 V *)
+15...+32 V
All 6 inputs
low – high switching threshold:
high – low switching threshold:
hysteresis:
input current (24 VDC):
switching delay 0-1 (24 VDC):
switching delay 1-0 (24 VDC)
13 V typically
6 V typically
7 V typically
7 mA typically
8 ms typically
8 ms typically

Negative voltage is restricted because of recovery diode (I
max
= 0.5 A)
Technical data on outputs
Number of outputs:
6 (2 + 4) electrically connected
source operation
not short circuit proof
Current:
5...500 mA steady load
Voltage range:
5...32 VDC *)
Potential drop:
< 0.3 V at 500 mA for E6 and E7
< 0.7 V at 500 mA for E/A2...E/A5
Current per module:
3 A steady load
Switch-ON:
10 μs typically
Switch-OFF:
50 μs typically (100 μs max.), (ohmic load 5...500 mA),
longer for inductive load because of recovery diode.
*)
If it is intended to read the status of a combined output, external voltage must be at
least 17 VDC, as both the status and the LED are displayed via the input.
