Wiring of coupler plugs (DO) for Y connector
To connect the digital outputs using a Y connector, you require:
A Y connector
Two M12 coupler plugs
A flexible, 3- or 4-core copper cable with a core cross-section of 0.75 mm
2
Wire the two M12 coupler plugs for the Y connector in accordance with the pinout
table below. The assignment of pin 4 depends on the socket of the ET 200X to
which you screw the Y connector.

Wiring the M12 coupler plug for analog inputs and outputs
To connect the analog inputs and analog outputs, you require:
A 4- or 5-pin, M12 coupler plug
A shielded 4-core copper cable with a core cross-section of 0.75 mm
2
Wire the coupler plug in accordance with the pinout of the sockets on the
expansion module. You will find the pinout in the information on the various
modules as of Section 7.21.9. You may have to connect the expansion module to
