Figure below illustrates one method of supplying a Remote Interlock signal using a customer-supplied
limit switch. Firestar’s +24 VDC Auxiliary Power output powers the circuit. Note that Pin 4, +5 VDC Auxil-
iary Power, could have been used instead, depending on circuit voltage requirements.
Figure 4-10 Customer-supplied interlock
Figure below shows another variation for supplying a Remote Interlock signal to the laser. In this case,
the customer is using a limit switch and supplying a negative voltage to drive Firestar’s input circuit.

A Programmable Logic Controller (PLC) can also drive Firestar inputs. Figure below shows a typical
method for connecting to a PLC output module when only one Firestar input is used.
