4.6 Wiring
Y- connection
The Y-connection allows you to connect two actuators or sensors to the inputs or outputs of
the I/O devices.
The use of a Y-cable or the Y-connector is particularly recommended when two channels are
occupied for each socket of an I/O device. The Y-cable or the Y-connector distributes the two
channels to two circular connectors.
