温度转换器 HiC2081

来源:未知    日期:2017/08/10    浏览量:


倍加福隔离式安全栅不但有限能的功能,还有隔离功能,它主要由回路限能单元,信号和电源隔离单元、信号处理单元组成。隔离式安全栅采用了将输入、输出以及电源三方之间相互电气隔离的电路结构,同时符合本安型限制能量的要求。

H 系列可将多个隔离栅安装在端子板上,连接危险区现场设备和控制系统。与单一接口模块相比,端子板极大地简化接线,节省了成本。   端子板配有坚固的塑料机壳,便于在机柜内快速稳固的安装。在端子板上有多个安装卡槽,工程人员不必使用工具即可将隔离栅安装在端子板上。隔离栅模块支持热插拔。可选的故障监测端子板使得操作及维护更加快捷。

配有电缆连接头的预置电缆可以简化设计和文档管理。这些电缆代替了端子板与控制器I/O卡件(DCS,ESD)之间繁杂的点对点接线.

信号转换器将危险区的仪表信号,例如温度、传感器、电位计等信号转换调节成为成比例的0/4…20mA信号或者 0/2…10V信号。
