      Universal USB Communications Kit

        Out of stock. Pre-order available.

    This versatile 2-wire transmitter accepts a range of standard input types, and outputs a 4-20mA loop. USB programming is hassle free, and takes less than a minute using Define ToolBox.

    • 2-wire universal transmitter (DIN-mount, isolated)
    • Current, voltage, thermocouple, RTD and potentiometer input
    • Loop powered, 4-20mA output
    • LED indicator for error notification
    • Potentiometer for fine offset adjustment of current output

    Easy USB programming using Define ToolBox

    • No power supply or calibrator required
    • Uses the universal USB Bridge Key (sold separately) for PC connection

    In addition to this software a Bridge Key is required for the configuration of this product. You must order one unless you already have one from a previous product purchase.
