Closing unused sockets
Sockets which are not used must be closed with M12 covering caps so that protec-
tion rating IP65 is ensured.
Y connection piece
A Y connection piece permits double connection of actuators or sensors to the in-
puts or outputs of the ET 200R.
We recommend using a Y connection piece when 2 channels per socket of a mo-
dule are being used. The Y connection piece divides the two channels into 2 coup-
ling plugs (for pin allocation see tables 4–3 and 4–4).

Y connection piece
Wire the two M12 coupling plugs for the Y connection piece as specified in the fol-
lowing pin allocation. The allocation of pin 4 of the Y connection piece depends on
the socket of the ET 200R into which you will screw the Y connection piece.
