| HD5544 REPEATER POWER SUPPLY | ||||||||||||||
| 1 | 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. | |||||||||||||
| 2 | Number of channels 2 Location of transmitters Zone0, IIC, T4-T6 hazardous area Div 1, Group A, hazardous location Safe-area output Signal range: 4 to 20mA Under/over-range: 0 to 24mA Safe-area load: 0 to 360Ω @24mA 0 to 450Ω @20mA Safe-area circuit output resistance: > 1MΩ Hazardous-area input Signal range: 0 to 24mA Transmitter voltage: 15V at 20mA Transfer accuracy Better than 15μA Temperature drift Better than 1μA/℃ Response time Settles to within 10% of final value within 750μs (In case of 250Ω typical safe-area load) | |||||||||||||
