Binary outputs signals (PL 100 B: A0 to A30, A32 to A62; PL 110 B: A0 to A24, A32 to A56 and "Emergency
stop")
Nominal voltage: 24 V, -
Max. difference to supply voltage: d 3 V
Max. output current: 1.2 A
Permissible loading: Resistive load; inductive load only parallel to inductivity with quenching diode, max.

Bipolar outputs (P L 110 B : A25 to A30 and A57 to A62)
Nominal voiltage: 15 V -
(measured between two bipolar outputs, with one output switched to signal "1" and the other to signal "0")
Nominal current: 300 mA
Voltage range with nominal current: 14.0 V to 15.5 V
Max. output current 1.2 A for 1 minute
Current limitation range: 1.35 A to 1.6 A
Permissible load: Resistance load;
inductive load only with quenching diode parallel to inductivity
max. switching frequency: 50 Hz
Please note:,
Bipolar PLC-outputs may not be switched in parallel.
When using the bipolar outputs as binary output signals:
Voltage for signal "1": ~14.2 V
Voltage for signal "0": -=. 3.0 V
Nominal current: 300 mA
Max. output current 1.2 A for 1 minute
Output current supervision
Supervision of output currents of all bipolar outputs. Output J3/11 provides signal "1" if the sum of the out-
put currents of all bipolar outputs is -0.8 A to 0.9 A
Nominal voltage: 24 V -,
Max. output current: 55 mA to 65 mA
Max. difference to supply voltage: < 1.5 V
