Connecting the sensors
Four sensors and four additional inputs or outputs (AUX I / O) can be connected to the "Sensor
1, I / O 1" to "Sensor 4, I / O 4" connections. PNP or NPN sensors as well as sensors with NC or
NO contact can be used. The sensor type and the function of the additional I/O can be
parameterized (see "Digital I/O Settings", page 32). Using a Y-line, a sensor and an input/output
can be connected to one connection at the same time (see „Accessories“, page 57).

NOTICE
Connections are not short-circuit proof
In the event of a short circuit, in particular between pin 1 and pin 3, the internal fuse
(PTC) in the MultiControl triggers. Normal operation is possible again after the internal
fuse has cooled down.
➢ Ensure correct polarity.
The inputs and outputs are not electrically isolated.
Characteristic values for the inputs
Input voltage
0 V to 24 V DC
