The SB3043 provides a fully floating dc supply for energizing a conventional 2- or 3-wire 4/20mA transmitter located in the field and repeats the current in two floating circuits to drive different control-station loads. The SB3043 provides dual outputs. HART is repeated through channel 1 only for bi-directional communication
