These models are used to drive resistive loads (sources current). The 4-20mA output signal and DC power share a common lead which is wired directly to the PLC/DCS's internal ground. Acromag's 340i model is ideal for applications requiring multiple isolators at a single location where all isolators share the same power supply. PLCs and DCSs usually have 24V DC power available at their input terminals.

    • 4 to 20mA DC output
    • 10-36V DC power
    • 1500 AC peak isolation prevents ground loops
    • Calibration is independent of the load to eliminate load compensation adjustments
    The 340i accepts a process current input and provides an isolated 4 to 20mA process current output signal.
