Description

MTL-5541 中继器电源

MTL-5541提供了一个全浮式直流电源，用于激励传统的2线或3线4/20mA发射机，该发射机位于危险区域，并在另一个浮式电路中重复电流以驱动安全区负载。对于HART 2线发射机，该单元允许在4/20mAloop电流上叠加双向通信信号。另外，MTL5541S-T作为安全区域连接的电流接收器，而不是将电流驱动到负载中。可以连接单独供电的电流源，如4线变送器，但不支持HART通信。

The MTL-5541 provides a fully-floating dc supply for energising aconventional 2- or 3-wire 4/20mA transmitter, which is located in ahazardous area, and repeats the current in another floating circuit todrive a safe-area load. For HART 2-wire transmitters, the unit allowsbi-directional communications signals superimposed on the 4/20mAloop current. Alternatively, the MTL5541S-T acts as a current sinkfor a safe-area connection rather than driving a current into the load.Separately powered current sources, such as 4-wire transmitters, canbe connected but will not support HART communication.
