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。
远程I/O适用于位于爆炸危险区或者严酷工业环境的应用，例如海洋平台和户外。典型的应用行业包括石油天然气（内陆及海洋）、制药、化工、污水处理、食品饮料等。
FB远程I/O可安装在危险区Zone1或Zone21区。信号调节模块可以将现场信号转换并传递到安全区的控制系统中。FB远程I/O通过标准总线技术（Profibus，Modbus and several other）将传统传感器和执行机构连接到DCS系统输入/输出模块在系统中允许带电插拔而无需获得带电操作许可。
多种单通道/多通道I/O模块具有本安型接口和增安型接口，分别连接本安型现场仪表和隔爆型仪表。远程I/O系统可以很容易的满足用户工程的需求。
频率/计数器输入模块用于频率测量，脉冲记数和转向检测的单通道模块。
