模拟量输出模块 LB4002A2

来源:未知    日期:2017/06/15    浏览量:


模块化的远程I/O系统通过总线接口将现场二进制和模拟量的传感器和执行器连接至控制系统的方式传输安全区域或者爆炸危险区域的现场过程数据。模块化的远程I/O系统通过总线接口将现场二进制和模拟量的传感器和执行器连接至控制系统的方式传输安全区域或者爆炸危险区域的现场过程数据。

可以将4 ~20 mA设备连接到远程I/O,例如流量变送器、阀门定位器、压力传感器或者温度变送器。诸如热电偶(TCs)、电阻式温度检测器(RTDs)、机械触点以及声光报警器等设备也可以连接到远程I/O。我们的远程I/O系统能够兼容PROFIBUS DP, MODBUS RTU, MODBUS TCP/IP 和 FOUNDATION fieldbus等网络协议。

LB远程I/O系统能够安装于危险区 Zone2或者Zone 22以及安全区。该系统是模块化的信号处理系统,是现场信号和安全区的控制系统之间的接口界面。LB远程I/O系统通过标准的总线通讯协议(PROFIBUS, Modbus 等),将传统的传感器和现场设备的信号传送给DCS。可插拔的输入和输出模块能够在线热插拔。

单通道和四通道模拟量输出模块用于控制0/4-20mA HART定位器,比例阀和指示仪。
