Figure below illustrates one method of supplying a Remote Interlock signal using a customer-supplied
limit switch. I401’s +24 VDC Auxiliary Power output powers the circuit. Note that Pin 4, +5 VDC Auxiliary
Power, could have been used instead, depending on circuit voltage requirements.

The 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 I401’s input circuit.
