    What it does:
    Enables sophisticated monitoring, control and data logging of up to 16 input signals from a variety of sources

    Easy DAQ and onboard data logging

    Get all your data acquisition (DAQ) requirements fulfilled with the Zen Datalogger. It logs data onto a 1GB micro SD card, so you can physically take your data with you or route it to other hardware.

    Data visualization and graphing helps you understand your data

    If logging data is vital to your application then you'll know that interpreting that data is just as vital. The Zen Datalogger gives you a simple way (via WorkBench software) to plot graphs and visualize your data for a better understanding of your results.

    “We've had a Define data logger in operation for more than a year now and it has been running flawlessly since the day of commissioning.” Columbus Steel

    Enjoy the flexibility of universal inputs

    Like its predecessor (ZEN-16) the Zen Datalogger accepts TC, RTD, mA, mV, V, Frequency and Counter and shares many of its capabilities. This means you can reduce the number of separate instruments you need for your application, keeping things simple for maintenance and troubleshooting.

    • 16 isolated channels
    • 4 digital inputs, 2 analog ouputs, 2 relay outputs
    • RS232/RS485 and RS422/R485
    • Ethernet Modbus
    • HMI interface
    • Expansion option to ZEN-RIO

    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.
