Adamkse Posted January 20, 2020 Report Share Posted January 20, 2020 Hi, I now have my Remote I/O module connected and communicating correctly but I now have an issue with the Analog Input module. I have some 4-20mA transmitters wired up to the inputs but the LEDs are all blinking. The manual suggests that it is because the field power is no connected. This is correct as the device is powered from another 24V supply. Any ideas? Any helps is greatly appreciated. Cheers, Adam Quote Link to comment Share on other sites More sharing options...
bobnorway Posted January 21, 2020 Report Share Posted January 21, 2020 We had a similar problem a while back and ended up puting an optical isolator between the sensor and the Unitronics. Quote Link to comment Share on other sites More sharing options...
