Nominal values and tolerances
External voltage supply for PLC
Nominal voltage: 24 V, -
Voltage range: 20.4 V to 28.8 V
Furthermore, superimposed alternating voltages with a relative oscillation width of 10 % - related to the average
DC-voltage value - are permissible.

Binary input signals (EO to E62 and E64 to E 126)
Nominal voltage: 24 V, -
Voltage range for signal "1": 16.5 V to 30 V
Voltage range for signal "0": - 3 V to + 4 V
Current range for signal "1": 6.2 mA to 12.6 mA
Please note:
Interference signals ~1 rns at the PLC-inputs are filtered with a Schmitt-Trigger-input circuit. Long duration
interference signals must be with software.
Binary outputs signals (PL 100 B: A0 to A30, A32 to A62; PL 1 IO B: A0 to A24, A32 to A56 and "Emergency
stop")
Nominal voltage: 24 V, -
Max. difference to supply voltage: L 3 V
Max. output current: 1.2 A
Permissible loading: Resistive load; inductive load only parallel to inductivity with quenching diode, max.
switching frequency: 50 Hz
Please note:
Adjacent PLC-outputs (e.g. A7 with A8) can be switched to parallel via resistors e.g. 2 x 0.472.
