IS420UCPAH2A

IS420UCPAH2A is one of two UCPA controllers available for the Mark VIe system. These controllers include a BPPC processor board and a STWC base I/O board. The IS420UCPAH2A also includes a WEXP extended I/O board. The board adds six analog inputs to the two existing analog inputs on the STWC board. It also adds two analog outputs and four discrete I/ OS (out of a total of eight in the system). Some of these I/O points can be configured point-by-point. I/O configuration is usually done through the hardware TAB using the ToolboxST component editor.
