MTL5541 Repeater Power Supply
Brand: Status InstrumentsThe MTL 5541 provides a fully floating dc supply for energising a conventional 2 or 3-Wire (4-20) mA transmitter which is located in a hazardous area, and repeats the current in another floating circuit to drive a safe area load.
For smart 2-Wire transmitters, the unit allows bi-directional communications signals superimposed on the (4-20) mA signal.
Features- Powers a 2/3-Wire (4-20) mA transmitter in a hazardous area
- Repeats the transmitter signal into the safe area
- Also suitable for hart transmitters
- 20-35 Vdc power supply
