MTL5541 Repeater Power Supply

Brand: Status Instruments

The 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
