Wiring of M12 coupler plug for digital inputs
To connect the digital inputs, you require:
A 5-pin, M12 coupler plug, possibly integrally molded
A flexible 3-, 4- or 5-core copper cable with a core cross-section of 0.75 mm
2
Wire the coupler plug in accordance with the pinout table below. The pinout of the
sockets X1 to X4/X8, which are used for the inputs on the ET 200X, is shown
together with the data for the individual modules in Section 7.1 ff.

* Made available by the ET 200X for the connected sensor
** Only relevant if socket has 2 assigned channels
Note
If a sensor has a normally-closed contact and a normally-open contact, the
normally-closed contact is automatically wired to pin 2. The channel assigned to
pin 2 can thus no longer be used for the adjacent socket.
