MTL中继器电源MTL5541S技术参数

MTL中继器电源MTL5500系列介绍

应用与功能

模拟输入模块MTLx541（单通道）和 MTLx544（双通道）是本质安全型隔离器，可与位于过程工厂危险区域的过程测量变送器连接。它们按照IEC 61508 标准设计和评估，适用于最高 SIL3 安全等级的安全仪表系统，无需硬件冗余。

每个模块均提供完全浮动的直流电源，用于为传统的两线制或三线制 4-20mA 过程变送器供电，同时将现场回路中的电流重复分配到另一个浮动电路，以驱动安全区域负载。MTLx544D将单个现场回路中的电流重复分配到两个隔离的安全区域负载。对于使用HART协议的“智能”两线制变送器，这些模块允许在 4-20mA 信号电流上叠加双向通信。模块上无需设置任何配置开关或操作员控制。

Application and function

The analogue input modules, MTLx541 (single channel) and MTLx544 (dual channel) are intrinsic safety isolators that interface with process measurement transmitters located in a hazardous area of a process plant. They are also designed and assessed according to IEC 61508 for use in safety instrumented systems up to SIL3, without hardware redundancy.

Each module provides a fully-floating dc supply for energising conventional 2-wire or 3-wire 4-20mA process transmitters while repeating the current flowing in the field loop into another floating circuit to drive the safe area load. The MTLx544D repeats the current flowing in a single field loop into two isolated safe area loads. For‘smart’ 2-wire transmitters using the HART protocol the units allow bi-directional communications superimposed on the 4-20mA signal current. There are no configuration switches or operator controls to be set on the modules.
