Remote I/O Systems

  • Transmit process data from safe or explosive hazardous areas by connecting binary and analog sensors and actuators to the control system via a bus interface.
  • Put I/O modules close to the field devices.
  • Reduce cost of wiring and installation - field units can be installed in a decentralized location inside hazardous areas while monitored from a control room.
  • Connect 4 mA … 20 mA devices to remote I/O, including water flow transmitters, valve positioners, pressure transducers, temperature transmitter, thermocouples, resistance temperature detectors (RTDs), mechanical contacts, and visual or audible alarms.
  • Compatible with network protocols like: PROFIBUS DP, MODBUS RTU, MODBUS TCP/IP, FOUNDATION Fieldbus H1
