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。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。
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
方便连接I/O模块的FB DCS系统远程I/O的解决方案,SCADA系统,或PLC,倍加福提供com单元模块(网关)额定用于Zone 1 explosion-hazardous地区。
