At a Glance

    • Interconnect a digital 20/30/60-mA unipolar Current Loop interface to an RS-232 interface
    • Configure this AC-powered converter to match your system's 20-, 30-, or 60-mA Current Loop interface.
    • Has built-in optical isolation on the receive pair.
    • DCE/DTE switch for easy direct connection no special cables needed.
    • Two LEDs monitor data flow.


    • Optical isolators in both the Transmit and Receive loops keep out electrical interference.
    • AC-powered, active or passive.

    With front-panel LEDs, you always know the status of your data. The easy-to-use self-test feature checks the converter's internal circuitry.

    Connect this converter to either a modem or mux. Just flip the switch to attach a terminal or computer. Your RS-232 devices are protected from dangerous transients, too.
