BASIC INFO

MTL5541 Repeater Power Supply 4/20mA HART for 2 or 3 Wire Transmitters

The MTLx541 provides a fully-floating dc supply for energising a conventional 2- or 3-wire 4/20mA transmitter, which is located in a hazardous area, and repeats the current in another floating circuit to drive a safe-area load. For HART 2-wire transmitters, the unit allows bi-directional communications signals superimposed on the 4/20mA loop current. Alternatively, the MTLx541S acts as a current sink for a safe-area connection rather than driving a current into the load. Separately powered current sources, such as 4-wire transmitters, can be connected but will not support HART communication.

The following guide is for users who require guidance on their choice of isolator for a new installation. For a given application the choice is between DIN-rail mounting (MTL5000/MTL5500 range) and backplane mounting (MTL4000/MTL4500 range) devices.

Analogue Inputs (high level)	 2-wire transmitters, 4-20mA conventional and 'smart'  vibration transducer  loop isolator
Analogue Inputs (low level)	 thermocouples and mV sources  2, 3 and 4-wire RTDs  strain-gauge bridges
Analogue Outputs	 controller outputs (I/P converters)
Digital (ON/OFF) Inputs	 switches/proximity detectors
Digital (ON/OFF) Outputs	 switches, proximity detectors, SIL3  alarms, LEDs, solenoid valves, etc.  switch output to hazardous area
Pulse Input	 turbine/flowmeters
Miscellaneous	 fire/smoke detectors  signal transfer  trip amplifiers  earth leakage detector
