micapp Posted March 25, 2023 Report Share Posted March 25, 2023 See enclosed picture. Is this correct use of analog input? And on second picture: Is this the correct use of analog output? Link to comment Share on other sites More sharing options...

micapp Posted March 25, 2023 Author Report Share Posted March 25, 2023 nd this is what i find difficult to understand. Normally I connect my two-wire sensor to + 24V and i.e. input CH1 (on picture), but this looks like the sensor shall connect +24V to CH1 and the low side to 0V ?

And on second picture: Is this the correct use of analog output? Yes* and yes. The manual is clearly wrong. The Ethernet I/O is not a Unitronics-manufactured product, and the manual is not an original complete creation of the Unitronics documentation department. It is a modified re-issue of what the manufacturer supplied. So somebody missed something. Too many late nights and deadlines on the tech writers, I would suspect. Thanks for pointing this out. Flex has already flagged Cara Levy the Documentation Queen so hopefully it gets corrected and updated soon. Joe T. * - that is correct for a two-wire device. Some devices require separate power and generate their own current rather than modulating their supply. Link to comment Share on other sites More sharing options...
