Pin layout of PLB 620x:
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
consequence of excessive temperature, the individual PLC outputs switch off
automatically. Then the outputs will try to switch on again cyclically. Seven
outputs and twelve inputs are available at X9 of a PLB 620x for free use.
Further PLC inputs/outputs must be realized by means of I/O modules.
OLD connector/signal design.
