User I/O connections
A Programmable Logic Controller (PLC) can also drive I401 inputs. Figure below shows a typical method
for connecting to a PLC output module when only one I401 input is used.
Figure 4-12 PLC driven interlock signal
When multiple PLC outputs are used, connect I401 inputs to the PLC as shown in Figure 3-13. 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.
