Product Details

HD5544 REPEATER POWER SUPPLY

The HD5544 provides 2 fully floating dc supply for energizing 2 conventional 2-wire 4/20mA transmitters located in a hazardous area and repeats the current in another 2 floating circuit to drive 2 safe-area loads. For smart 2-wire transmitters, the HD5544 allows bi-directional HART communications signals superimposed on the 4/20mA signal.
