Example 2
To connect to an NPN-compatible PLC input, connect Output 0 or Output 1 directly to the
PLC input. When enabled, the output pulls down the PLC input to 0V.

Example 3
High-Speed outputs can also be used with a PNP-compatible PLC input if a pull-up resistor
(for example, 2.2k 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.
