Electrical Connections for Sensor Port Aux I/O
When connecting to either the Left Sensor or Right Sensor port with an M8 connector to access the Aux IO signal; you typically will use a standard parallel type splitter cable assembly that breaks out each of the available pins on the Module to their own M8 connection port. These splitter cables wire the +24V and Common connections in parallel.
*Splitter cables are commercially available from multiple sources.
Pulseroller IOX-2 Breakout Module also provides the same splitter functions as well as other functions.

Aux I/O Pin 2 as Input
When the Aux I/O Pin is configured as an input, the circuit is NPN/PNP auto-sensing. The signal can be connected to either +24V or 0V to operate.
*You can use this connection for any Input Signal as shown in the Aux IO Signal Chart from the EasyRoll+ manual.
*You can also directly connect any compatible M8 style sensor for any Input Signal where a sensor will provide the desired function.

!Because the auto-sensing circuit requires a nominal voltage in order to operate, there will be some small amount of leakage current possible between Module Pin 2 and Pin 3 (GND). Please use caution if you connect a load between Module Pin 2 and Pin 3.
Aux I/O Pin 2 as Output
When the Aux I/O Pin 2 is configured as an output, the circuit is NPN only and requires the load to be connected to Pin 1 (+24V)
*You can use this connection for any Output Signal as shown in the Aux IO Signal Chart from the EasyRoll+ manual.
![]()
!PLEASE NOTE: The output is limited to 20mA and is NPN Only. It is recommended that you use the IOX Interface Module if your output needs to provide more power and/or if it needs to be PNP.
