توضیحات
Function:
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.
