HE iDCS-8830 modular remote redundant I/O system supports Modbus/TCP and Modbus/UDP with 8 I/O slots designed to work in duplex or simplex applications. It is available now from ICP Electronics Australia .
It provides easy installation of the I/O modules and process cabling. The system is highly modularized and flexible, so that the I/O modules can be combined to suit many applications including most types of signals, digital, analog, counter and HART.
The station of the I/O system consists of power modules, communication modules, I/O modules and termination boards. The power modules provide the isolated power to the system.
The communication modules are the interface to the iDCS-8830 I/O modules and the iDCS-8830 I/O modules sense or control the device in the field. Termination boards are used to connect between signals to/from the field and I/O modules.
All of this supports Hot-Swap allowing modules to be replaced. The communication component of this system comprises a pair of partnered Ethernet adapter modules that communicate with Modbus/TCP or Modbus/UDP protocol, and the I/O modules that are configurable in simplex or duplex modes. This system supports max 4 redundant pairs of I/O modules that work in Duplex mode.
