To connect Output 0 or Output 1 to a relay, LED, or similar load, connect the negative
side of the load to the output and the positive side to +24V. When the output switches
on, the negative side of the load is pulled down to 0V, and 24V appears across the
load. Use a protection diode for a large inductive load, with the anode connected to the
output and the cathode connected to +24V.

In-Sight 1000 outputs can also be used with PNP-compatible PLC input if a pull-up
resistor (for example, 2.2kW 0.5W) is connected from the output to +24V. In this case,
the resistor supplies 24V to the PLC input. The output will pull the voltage down to 0V,
turning off the PLC input. This creates an inversion, with the PLC input ON when the
In-Sight output is OFF, and vice-versa. Use an external NPN to PNP converter when
this inversion is not desired.
