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

The
HSOUT
status LEDs on the In-Sight 3400 sensor indicate the state of the outputs. The LEDs
will illuminate when the outputs are actively pulled low (NPN type output).
