The iDCS-8830 remote redundant IO unit is available in a dual redundant configuration with Modbus TCP protocol. This consists of two communication processors installed in the same backplane. In addition to the communication processors and powers, up to 8 IO modules can be installed in the backplane. These IO modules can be configured as individual IO modules or configured as redundant IO modules. There is up to four groups of redundant I/O modules can be used in the iDCS-8830. When one of modules in the iDCS-8830 has a failure, the other backup module would take care of the work seamlessly. That can guarantee the reliability of the system. The iDCS-8830 offer redundancy options for various functions- ranging from power redundancy to I/O redundancy. Besides, there are most of I/O modules, such as DI, DO, AI, AO, PI, PO, HART and etc, can be used in the iDCS-8830. Therefore, the iDCS-8830 is fit for the high safety applications especially in DCS applications. Moreover, due to the open Modbus TCP protocol, most SCADA software built-in Modbus communication protocol can easily and quickly integrate the iDCS-8830 to the SCADA software as data acquisition and monitor to apply to environment monitoring, power management, factory automation, etc. With the above features, the iDCS-8830 is a high safety, reliability remote I/O system.
