• 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 combined 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 pin supplies power to the node electronics. This pin must be
powered at all times for communication node to be functional.
