The iDCS-8000 is a modular remote I/O system. It provides easy installation of the I/O modules and process cabling. It is highly modularized and flexible, so that the I/O modules can be combined to suit many applications including the most types of signals, digital, analog, counter and HART. The station of an iDCS-8000 system consists of power module, communication module, I/O modules and termination board. The power module provides the isolated power to iDCS-8000 system. The communication module is the interface to the iDCS-8000 I/O modules. The iDCS-8000 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 these modules can be configured into single or redundant operation.
