  • SLIM-5I 4-20mA Isolator, 5 Channels Loop Powered Output

    Din Rail Mounting, Ultra-Slim (0.5") Case

    SLIM-5I 4-20mA Isolator, 5 Channels Loop Powered Output. Find out everything you need to know about the Define Instruments SLIM-5I in just 30 seconds with our quick video overview.

    What it does:
    This loop powered isolator receives 4–20mA process current inputs, and provides 4–20mA loop powered output signals.


    It is ideal for measuring signals commonly produced by position, acceleration, current, and a vast range of other industrial sensors, and offers a low cost isolation solution with top-of-the-line specs.

    At a glance:

    • 5 x 4–20mA DC input
    • 5 x 4–20mA DC output (loop powered)
    • Lightning fast 2msec response time Ensures accurate measurement of rapidly changing signals
    • No fuss installation No DIP switches, no calibration, simple wiring
    • High accuracy – better than 0.05%!
    • Superior noise resistance Designed for stable, accurate performance, even in noisy environments, with excellent resistance to electromagnetic interference
    • 5 isolated channels in a compact 0.49" case - Industry leading 0.098" DIN space per channel!

    Along with high speed, accuracy and stability, it also offers input and output protection for polarity and inadvertent connection to 30V DC. With 5 independent channels which are isolated up to 2.5kV, your control system will be protected from transients and noise:

    • No more signal cross talk
    • No more ground loops
    • DC/AC common mode voltage rejection
    • Over range protection
