Pin layout of PLB 620x FS:
The triggering outputs at X9 each supply up to 150 mA of output current. The
only exceptions are the two outputs –STOS.A.G and –STO.A.G with max. 2 A
of output current. In the event of an overload or short circuit and as a conse-
quence of excessive temperature, the individual PLC outputs switch off auto-
matically. Then the outputs will try to switch on again cyclically.
Two outputs and six inputs are available at X9 of a PLB 620x FS for free use.
Further PLC inputs/outputs must be realized by means of I/O modules.
