Connector Pin-Outs
Industry standard connectors are used for communication and power. The PROFIBUS-DP communication
connectors are a M12 reverse key 5 pin male connector and a M12 reverse key 5 pin female connector. The
Power connector is a 7/8” MINI 5 pin male connector.

!
 Power common (0 VDC) pins 1 and 2 are isolated from each other to allow
separate (isolated) power supply connection if required. However, they can be
tied together if a single common, non-isolated, application is preferred.
 The draw of the +24VDC Valves and Outputs and +24VDC Node and Inputs
pins cannot exceed 8 Amps, at any given moment in time.
 The Node and Inputs pins supplies power to the node electronics. These pins
must be powered at all times for communication node to be functional.
