    • Bridge Key - $

      Universal USB Communications Kit

        Out of stock. Pre-order available.

    What it does:
    Enables sophisticated monitoring and control of up to 16 temperature input signals from a variety of sources.

    Get 16 RTD signals into your PLC or SCADA system

    If you need to collate multiple temperature signals and route them to your PLC or SCADA system, choose the Zen RTU/R. This exceptionally flexible and powerful monitoring and control station is the last word in RTU technology.

    Why pay more for channel isolation you don't need?

    The Zen RTU/R is designed specifically for applications with temperature signals. It has non-isolated inputs specifically for PT100 / PT1000 RTD signals.

    Set up in just minutes

    No calibration and simple software set up with WorkBench.

    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.
