Blitz Posted April 13, 2017 Report Share Posted April 13, 2017 Hi, the existing installation consists of eight PT100 sensors connected to a Digital indicator with 3 wire runs for each sensor. I intend to replace the Digital indicator and use IO-PT400 and V130. However, the IO-PT400 manual appears to suggest only 4-wire RTD connections. So my question is whether I can use the IO-PT400 with 3-wire RTD only. If so, should I jumper +I and +V terminals or should I jumper -I and -V terminals on IO-PT400 end? Thanks.
