An example application of these signals is shown in Figure 15.
PLC Power channel is a 24V source available for use to drive
PLC logic but must be current limited using pull-down resistors
to protect the FX-1250 when directly attached to the I/O
channels through the PLC connector. The support current is
50 mA max
