6 TI 275281206 - 4912
The special wiring of the M12 round plug connector enables connection of both single and double
sensors, which are equipped with normal M12 system connectors in the standard sensor/actuator
configuration.
With the use of M12 round plug connectors, the terminal bar connectors for the digital inputs
(connection unit of the option) must not be used.
The LEDs between the plug connectors indicate the switching status of the IOs (top, from left to right
DIN1, DIN3, DOUT1 / bottom, from left to right DIN2, DIN4, DOUT2).

Connection examples
The following connection examples are generally applicable for NORD IO modules. The number or
type of the available IOs and their configuration on the terminal rail varies according to the module.
The actual availability or the designation of the individual contacts should be obtained by reference to
the description of the connections. The technical data (e.g. load capacity) must be taken into account.
