XTR115: XTR115 with the same Voltage isolated

David Escarpa

Part Number: XTR115
Other Parts Discussed in Thread: XTR117, XTR116, XTR111

I have three voltage oput from the DAC, to three differents XTR115. But, the three XTR115 have the same Voltage loop. Like this

But this is not working. But If i have only one XT115, works propertly. Is it needed a voltage loop for each XTR115??

Thanks

Hi David,

the interesting question is what you do with pin 3 of the several XTR115. Can you please post a complete schematic?

Hi David,

As Kai indicated that Iret or pin3 and pin4 have to be floating. XTR115, XTR116 and XTR117 are all 2-wire, 4-20mA current loop transmitters.

Also, see 4-20mA Basic.pdf file in the attachment link below.

Hi David,

as implied by Raymond, one remedy is to exchange the XTR115 by a 3-wire transmitter like the XTR111.
