A Programmable Logic Controller (PLC) can also drive inputs. Figure below shows a typical method for
connecting to a PLC output module when only one input is used.
Figure 4-12 PLC driven interlock signal
When multiple PLC outputs are required, connect inputs to the PLC as shown in Figure below. By
supplying voltage (+VDC) to Pin 11, Input Common, and pulling individual inputs to ground, each input
can be independently activated by the PLC's output module.
