Functional Description
The GE IS220YDOAS1A consists of an acquisition board and a common processor board, enabling control of up to twelve relays with feedback from terminal boards. Outputs are transmitted via a DC-37 pin connector for direct connection.
It supports both TMR (Triple Modular Redundancy) and simplex configurations. In TMR setups, three I/O packs are required, while simplex requires only one. Built-in self-diagnostics include power-up tests for processor hardware, flash memory, Ethernet ports, and RAM, with results accessible through ToolboxST software.
Applications and Compatibility
The IS220YDOAS1A is widely used in GE Mark VI/EX2100 turbine control systems for managing discrete outputs in gas, steam, and wind turbine applications. Its redundancy options, diagnostic features, and LED indicators ensure reliable performance and simplified maintenance in industrial automation environments.
