Appendix A – Module Specifications
Publication ERSC-1008 Rev 1.1 – October 2017
• PNP/NPN Auto-sensing (Default)
• Up to 8 per module - 2 inputs per port
• Programmable Push-Pull selectable
Short Circuit protection( per side)
Sensor port inputs are auto-sensing for the connected circuit type of either PNP or NPN. Please note that both
sourcing and sinking current will activate the input.
Each port utilizes load detection circuits between the +24V (Pin 1) and Gnd (Pin 3). This circuit provides input to
the processor to detect if a power consuming device is connected. Short circuit between Pin 1 and Pin 3 can cause
damage to the load detection circuit and render this function inoperable.
