How to convert 4 wire input to 2 wire?
(OP)
Need your help folks.
I need to bring 4-20 signal from 4 wire current transmitter to 2 wire input card (Delta V). It was surprise for me that in Delta V i have to use a pair of cards for the same field signals. What are the options?
Thanks
BB

+ to the even pin - to the bussed power supply negative. You can easily check this out by measuring the resistance across these 2 points. If it's 250 Ohms you are in business.
I have attached a schematic of the 2 types.

That's what I was looking for. Hope I will be able to deal with these microscopic terminals and power termination of the carreer.
