5.5.2
Wiring the digital outputs
Switching behavior: push/pull
Electrical values
The sum current (100 mA) for all digital outputs is identical.
Push/pull
HIGH: U
V
−3 V; LOW: ≤ 3 V
In the case of a push/pull sensor, the signal must be inverted in the control system in
order to obtain the same result as a sensor with NPN switching behavior.
