properly wire a 2wire current loop device using Allan Bradley TB3 base analog card

[EthanB625]

I have attached two photos. One of a pressure transmitter wiring diagram (I am installing the current output 2wire loop) and a picture of a wiring schamatic for my analog flex I/O terminal base. My drawings on the job are showing to wire the 2wire device to the input terminal (strip A) and the other wire to the common -24v corisponding terminal (strip B) but my device needs a +24v feed. Maybe someone can clarify how to connect a 2 wire current loop device to a TB3 terminal base on a Allan Bradley analog card. I apprichate any help on this. Thanks

You need to wire a 24 volt DC power supply in series with the input card and the transmitter.
