2.2.2.2 Control connections for SK TU4-DEV(-…)
The double spring-loaded terminal bar of the technology unit is colour coded, and therefore indicates the three
different potential levels.
A separate voltage source can be used to supply 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.
Connection of up to 4 sensors and 2 actuators is made via the terminal bar. Alternatively, the
SK TU4-DEV-M12 module enables the connection of these I/Os via the M12 round plug connector (5 pin
socket, A-coded) mounted on the front.
