User I/O connections
A Programmable Logic Controller (PLC) can also drive Firestar inputs. Figure 3-12 shows a typical
method for connecting to a PLC output module when only one Firestar input is used.

When multiple PLC outputs are used, connect Firestar 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.
