4.3 PLC
Please note the following when connecting a higher-order
controller:
S
Use the PLC cable with 24-pin Binder plug supplied
(connection Checkbox PLC).
S
Wire the connections of the PLC according to the cable
assignments in Appendix A.4.
S
Make sure that the maximum sum current of 1 A is not
exceeded.
The reference voltage is provided at pin 4 (GND) and pin 7
(+ 24 V).
Under the following conditions, current-consuming devices
can be supplied with power via pin 4 (GND) and pin 7
(+ 24 V).
– Connect only current-consuming devices which return the
complete current to the Checkbox. In this way you can
prevent asymmetries in the currents in the outward and
return lines from reducing the effect of the filter.
– Load the output PLC_Power with maximum 700 mA.
