IS220UCSAH1A Processor/Controller

The IS220UCSAH1A is built as a single boxed component with a front faceplate to allow for connection of communications, two screw mounts on the rear edge, and grill openings on three sides to allow for air flow.  The controller is designed for base-mounting within a cabinet. Up to three components can be mounted adjacent to each other for a compact arrangement that easily serves triple redundant systems.

The IS220UCSAH1A works on a QNX operating system.  It has a Freescale 8349, 667 MHz processor. The board uses a power source rated at 18-36 V dc, 12 watts. The board can be used in temperatures from 0 to 65 degrees Celsius and does not require a fan for cooling, even at max temperature rating.   The board can be used for NFPA Class 1, Div. 2 applications.

The front faceplate of the IS220UCSAH1A has six female jack connectors, one USB port, and multiple LED indicators.  This includes LED indicators down the left side of the front panel labeled Link/Act, and a line of indicators placed in the middle of the faceplate that are labeled Power, Boot, Online, Flash, DC, and Diag.  Jack connectors are used for Ethernet connections, which allow the board to communicate with other MKVI, MKVIe, or EX2100 excitation controls, along with maintenance stations and operator stations.
