Y cable
The Y cable allows you to connect two actuators or sensors to the inputs or outputs of the
ET 200eco PN.
The use of the Y cable is particularly recommended when two channels are occupied for
each socket of an I/O device. The Y cable divides the two channels for two jacks (for pin
assignment, see the tables below).
Figure 3-3 Y cable
The wiring of the Y cable is shown below.
Wiring jacks (DI/DQ) for Y cable
To connect digital inputs via a Y cable, you will need:
● A Y cable
● 2 M12 jacks
● A flexible 3-wire or 4-wire copper cable with a wire cross-section of ≤ 0.75 mm

The assignment of Pin 4 depends on which socket of the ET 200eco PN the Y cable is
screwed to.
Pin assignment of the sockets for inputs/outputs
The pin assignment of the sockets for inputs/outputs can be found in the data for the
individual I/O devices starting in sectionPin assignment of digital inputs (Page 41).
