Sensor Port I/O
Each Module is equipped with two 4-pin female M8 style Sensor I/O ports primarily used to connect a photo-
electric sensor to the module. Each of these ports has one pin dedicated as an input for the sensor (pin 4)
and one Aux I/O pin (pin 2) that is configurable to be either an input or an output.
Sensor Input Signal (M8 Pin 4)
The sensor input (pin 4) is auto-sensing for PNP or NPN circuit type such that both sourcing and sinking
current will activate the input based upon the following conditions:
Minimum ON Current 1.5 mA
Maximum OFF Current 0.4 mA
Aux I/O Signal (Pin 2) when configured as as INPUT
When configured as an INPUT, the Aux I/O (pin 2) is auto-sensing for PNP or NPN circuit type such that
both sourcing and sinking current will activate the input based upon the following conditions:
Minimum ON Current 1.5 mA
Maximum OFF Current 0.4 mA
Aux I/O Signal (Pin 2) when configured as an OUTPUT
When configured as an OUTPUT, the Aux I/O (Pin 2) provides an NPN only circuit as illustrated:
