dannykc Posted April 15 Report Share Posted April 15 Hi, What is Field Power? What is it for ? Is it possible to power the URA-0800O via the Filed Power bus from one power supply and the analog sensors from another? The common 0V of the two power supplies will be combined.

MVP 2021 Joe Tauser Posted April 16 MVP 2021 Report Share Posted April 16 Field power is what the modules use internally for the circuits connected to filed devices. Since the URA-0800O is an input module it won't be drawing directly from the Field Power bus. The A/D chips inside will be using "Field Power", but on this module the current input is actually creating a voltage drop across a shunt resistor. So as long as you connect your 0V terminals together as you describe you'll be fine. Joe T. Quote Link to comment Share on other sites More sharing options...
