NOTE
The data cables (Terminals 3/4 or Terminals 5/6) or the Terminals 1 and 2 to Terminal 11
are only contacted by mounting the bus module.
NOTE
Looping of the 24V supply voltage or GND is possible (except for Terminals 1 and 2),
however a maximum current load of 3A for the SK TU4-PBR(-
…) must not be exceeded.
Only adjacent terminals (e.g.: X5:11/12) may be used for looping.
Terminals 1/2 are preferentially for use with sensors and maximum loads of 500mA.
Details of the M12 connections of the SK TU4-
…-M12
The special wiring of the M12 round plug connector enables the 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
(Terminals 19, 20, 25, 26) must not be
