The double spring terminal bar is divided into 2 potential levels (system bus and digital outputs).
A separate power source should be used for the supply of the DOs. However, by bridging the 24V o and
GND o to one of the terminals of the system bus level (24V and GND) it is possible to implement the supply of
the DOs. 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.

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.
