Connector Pin-Outs
Industry standard connectors are used for communication and power. The PROFIBUS-DP
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.

pins cannot exceed 8 Amps, at any given moment in time.
The Node and Inputs pin supplies power to the node electronics. This pin must be
