can be powered by either 24 VDC via traditional discrete wiring or by approximately 48 VDC
delivered through the Ethernet cable from a PoE source. In either case the 4-20 mA analog output can
be used. This can be configured for sinking, sourcing or isolated operation. Below are some schematic
diagrams of typical electrical connection configurations.
