Input and output channels: I/O modules typically have multiple input channels and output channels for connecting various sensors and actuators. The input channel is used to receive external signals, while the output channel is used to send signals or control commands to external devices.
Communication interface: Remote I/O modules usually have a communication interface, such as Ethernet, serial port, or other communication protocol, to communicate with the control system. This allows the module to be placed in a remote location and communicate with the central controller over the network.
Data acquisition and processing: Modules are typically capable of collecting, processing, and transmitting data acquired from sensors. This may include data filtering, calibration and processing.
Real-time control: I/O modules typically support real-time control functions to respond in real time to external events or signals when needed.
Programmability: Some remote I/O modules have programmable capabilities that allow users to customize configuration and control based on specific application requirements.
Reliability and durability: In an industrial environment, reliability and durability are key factors. These modules usually have features such as anti-interference, dust and water resistance and high temperature resistance.
Diagnosis and monitoring: Remote I/O modules often have diagnostic and monitoring capabilities to help users detect and resolve problems and provide status information.
