However, in this case it should be noted that there is an increased risk of introducing interference into the
bus cables.
Connection of up to 8 sensors and 2 actuators is made via the terminal bar.

Connection example: SK TU4-ECT to SK 205E
NOTE
Looping of the 24V supply voltage is possible, however a maximum current load of 3A for
the SK TU4-ECT(-
…) must not be exceeded.
Only adjacent terminals (e.g.: 11/12) may be used for looping.
Terminals 1/2 are preferentially for use with sensors and maximum loads of 500mA.
