      Universal USB Communications Kit

        Out of stock. Pre-order available.

    What it does:
    The TM-2HLI accepts an RTD or TC temperature input signal and outputs a 4-20mA signal.

    The TM-2HLI is a DIN B style head mount transmitter that accepts either an RTD PT100/1000 input signal, or a thermocouple input signal, and converts it to an industry standard 4–20mA output. The TM-2HLI offers 3750V AC isolation between the input and output.

    • High isolation
    • High accuracy 0.03%
    • Loop powered
    • Fast, hassle-free USB programming using Define ToolBox
    • Enhanced EMC specifications

    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.
