MTL2441B 4/20mA REPEATER POWER SUPPLY.

 

The MTL2441B provides a floating dc supply for energising a 2- or 3- wire transmitter in a hazardous area and repeats the transmitter current in another floating circuit to drive a safe-area load. The unit can be used with all 2-wire transmitters certified as suitable for operation with safety barriers having a safety description of 28V, 300Ω. Other applications include repeating the current flowing in an existing barrier-protected loop to provide a fully isolated output with a high load handling capability and passing measurement or control signals (when used with an MTL2442B isolating driver) through a hazardous area separating two safe areas. The MTL2441B supersedes the MTL2441 but is designed for 240/120V ac supplies only. For a dc powered model choose the MTL5042 or MTL5045.
