The double spring terminal block of the BUS -Adapter Unit is colour coded to indicate the three different
potential levels .
The field bus level is electrically isolated from the system bus level and must therefore be separately sup-
plied with 24VDC.
A separate voltage source should be used to supply the DOs. However, it is also possible to implement the
supply of the DOs by bridging the 24V 2 and 0V 2 with one of the terminals of the system bus level (24V and
0V). However, in this case it should be noted that this produces an increased risk of errors on the bus
cables.
The sensors and actuators are connected to the terminal block. Alternatively, the SK TU4-DEV-M12 module
enables connection of the digital I/Os via the M12 round plug connectors (Socket, 5-pin, A-coded) on the
front of the module.
Double use of the inputs via the terminal block and the M12 round plug should be avoided.
