  • Javelin 2-Wire Isolated Transmitter, Universal Input, 4-20mA Output

    DIN Mount, Loop Powered, Isolated

    Javelin 2-Wire Isolated Transmitter, Universal Input, 4-20mA Output. Find out everything you need to know about the Define Instruments Javelin in just 30 seconds with our quick video overview.

    What it does:
    The Javelin accepts one of several popular input signal types and outputs a 4-20mA signal. Input types: RTD, mA, V, Pot, TC

    The Javelin is a loop powered, isolated transmitter. One of its key features is its easy software setup using Define ToolBox. ToolBox enables simple and flexible programming of the Javelin in less than a minute, with no input signal or power supply required.

    At a glance:

    • 2-wire universal input: Accepts mA, V, mV, RTD, TC and potentiometer signals
    • 4–20mA current loop output
    • Isolation between input and output
    • High Accuracy 0.03%
    • Hassle-free DIN-rail mounting, with a space-saving (0.5" wide) case
    • Simple USB setup Using Define ToolBox and requires Bridge Key

    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.

    The Javelin offers flexible input options to suit a virtually endless range of industries. High quality signal conditioning is a popular application. Another widely used application is as a simple 4–20mA in, and 4–20mA out isolator, to protect inputs of PLC's and SCADA systems from ground loops, transients, and the effectsof EMC.

    The Javelin can also be used to convert other standard process signals (such as ±10V, 1–5V, and 0–10V) to a 4–20mA signal.

    More sophisticated applications are also catered to. For example, a level signal from an odd shaped tank can be converted to a 4–20mA signal representing volume, by using the in-built linearization table.

    How can we sell this product at this price?

    If you have been comparing the Javelin with other UL temperature transmitters in the market, you're wondering why this price is so competitive. You may also by wondering what corners were cut for us to reduce the price. The answer is NONE.

    You pay this price because...

    • Made in New Zealand, not Asia. We are the manufacturer and you're buying direct from our Dallas branch.
    • We don't have an army of distributors and so don't need to compensate for their heavy margin in our price
    • We don't need to employ a legion of phone support workers. Our products are so simple, we rarely receive tech support calls.
    • We almost never have product returns. Our products are very robust and so we don't need to cover this in our pricing either.
