    long distance transfer of analogue signal

    I ended up buying a slightly more expensive ABB type that can be selectred for any combination of input and outputs. I set it up on a bench with 0-20mA input and adjusted the offset and gain to give 4-20mA output. I'll connect it into the machine circuit next week. I'll get contractors to run...

    long distance transfer of analogue signal

    I have seen one in RS made by ABB (ISVR011714R1100) RS No 442-8907. It says it is a 3 way analogue convertor. I believe that this means the output, supply and input are all isolated? One last thing, does the supply for the output current loop come from the 24v device supply (sentance above...

    long distance transfer of analogue signal

    The transducer provides a 0-20mA signal to a PLC input. This is then processed in the PLC program to display it on a monitor along with lots of other data. I intend breaking into this near the PLC so that it is in series with the signal conditioner input. I don't want to affect anything on this...

    long distance transfer of analogue signal

    I have a transducer in a steam line near a corrugating machine that shows the steam pressure 0-16Bar on an operating desk. It says on the transducer 0-20mA, so I assume that 0mA =0bar and 20mA=16bar. I have been asked to get this signal sone 300metres to the boiler house for them to monitor...
