MTL4544S 模拟量输入隔离式安全栅

MTL4544S 模拟量输入隔离式安全栅

该MTL5544S提供完全浮动的直流电源，用于为位于危险区域的两个传统 2 线或 3 线 4/20mA 或 HART 变送器供电，并在其他电路中重复电流以驱动两个安全区域负载。 

MTL5544S 对于智能变送器，该装置允许双向传输叠加在MTL5544S 4/20mA 环路电流上的数字通信信号。

或者，该MTL5544S充当安全区域连接的电流吸收器，而不是将电流驱动到负载中。可以连接单独供电的电流源，例如4线制变送器，但不支持HART通信。

The MTL5544S provides fully floating DC power for powering two conventional 2-wire or 3-wire 4/20mA or HART transmitters located in the hazard zone and repeating current in other circuits to drive both safe-zone loads.

MTL5544S For smart transmitters, the device allows bidirectional transmission of digital communication signals superimposed on the MTL5544S 4/20mA loop current.

Alternatively, the MTL5544S acts as a current absorber for safe zone connections rather than driving current into the load. Individually powered current sources, such as 4-wire transmitters, can be connected, but HART communication is not supported.
