  • 4-20mA Circuit Wiring

    Hello,

    I've attached a picture of a pressure sensor that i have in a project. im using a Bx-08AD-1. I haven't seen one like this where the +24v signal is taken to the card, i've only seen it where the -24v signal is put to the card and the +24v signal is powering the loop. Take it theres still alot i haven't seen. Has anyone seen something like this? if so advice on wiring?

    Thanks

    The text in the manual says that the 'current receiver' (the PLC analog current input) can also be placed in the other side of the loop but they don't illustrate that wiring. From that illustration just swap the labels 'power supply' and 'current receiver'.

      Refer to Chapter 8: BRX Analog I/O Expansion Modules
      It gives all the information need to wire up, set up and configure the analog I/O.
