Remote I/O is a flexible, cost-effective and reliable solution for detecting and controlling signals in industrial automation. Remote I/O modules can be installed decentrally, thus reducing cabling and simplifying installation and maintenance.
How does Remote I/O work?
- I/O modules: These modules record the signals from sensors (e.g. temperature, pressure sensors) and control actuators (e.g. valves, motors). There are different types of I/O modules, including analog and digital, depending on the type of signals to be processed.
- Communication interface: The recorded signals are transmitted via a communication interface (e.g., PROFINET, EtherCAT or Ethernet/IP) to the central control system, e.g. a PLC (programmable logic controller). This interface enables bidirectional communication between the Remote I/O modules and the central controller.
- Bus coupler: The bus coupler connects the I/O modules to the industrial network. It handles communication between the individual modules and the central control unit.
Areas of application:
Remote I/O is used in a wide range of industrial and process automation systems to reduce the amount of wiring required. In the chemical and pharmaceutical industries, Remote I/O systems enable precise monitoring of production processes, and thus contribute to compliance with strict safety and quality standards. In the energy and utilities industry, Remote I/O is used in the operation of power plants, water treatment plants and distribution networks. Remote I/O is also used in the automotive industry in larger applications such as production lines and robot cells.
