Convertible I/O signal processor for process control network

The convertible I/O signal processor is convertible between different operational configurations for connecting a plurality of field devices to the I/O signal processor through selectable types of electrical connectors, such as cables, junction boxes, etc. The I/O signal processor includes a signal processing module connected to the signal processor and an interface module removably connected to the signal processing module. The interface module includes an electrical connector for receiving/transmitting I/O signals from/to the field device. The interface module and the signal processing module define an I/O channel extending between the electrical connector and the signal processor. An interface module in an embodiment includes an I/O module connector that enables a removable I/O module to be inserted into an I/O channel. 可转换I/O信号处理器可在不同的操作配置之间转换，以用于通过可选类型的电连接器(诸如线缆、接线盒等)将多个现场设备连接到I/O信号处理器。I/O信号处理器包括连接到信号处理器的信号处理模块以及可移除地连接到信号处理模块的接口模块。接口模块包括电连接器，以用于从现场设备接收I/O信号/向现场设备传输I/O信号。接口模块和信号处理模块限定了在电连接器与信号处理器之间延伸的I/O通
