Power over Ethernet (PoE)
The PoE card
B
supplies power through the Ethernet
connection, so that an external 24 V DC power supply for the
flowmeter is not required. The PoE card (B) converts the 37 to
57 V supply from the Ethernet cable to 24 V DC. This 24 V DC is
available from terminals V3 and V4 and connects to terminals 1+
and 2+, supplying power to the flowmeter. Each port supports
PoE.
The specification is in accordance with IEEE 802.3at/af. PoE
Class 0.
Dependent on how power is supplied over the Ethernet cable,
there are four possible configurations for connecting to the
ports of the PoE card.
Port/Pin Verion 1 Version 2 Version 3 Version 4
Port 1 X1 RD+ & Pwr+ Spare RD+ Pwr+
Port 1 X2 RD- & Pwr+ Spare RD- Pwr+
Port 1 X3 TD+ & Pwr- Spare TD+ Pwr-

CAUTION
When using PoE, make sure that the PoE card and the red
and blue wires within the transmitter’s termination area are
in place and connected correctly.
Terminal V3 connects to Terminal 1+ and Terminal V4
connects to terminal 2-.
When using PoE, do not connect any other external supply
power to the transmitter's power supply Terminals 1+, 2-.
