PRODUCT INFORMATION
Product Overview
The General Electric IS220YDOAS1A is a discrete output pack designed for Mark VI and Mark VIe systems. It provides an electrical interface between one or two I/O Ethernet networks and a discrete output terminal board. The hardware structure consists of an acquisition board and a common processor board. This pack can control up to twelve potential relays while receiving feedback directly from the terminal board.
The unit provides discrete outputs through a dedicated DC-37 pin connector linked directly to the terminal board. It supports simplex architectures using a single pack and Triple Modular Redundant configurations using three packs. Built-in diagnostics execute an automated power-up test covering processor hardware, flash memory, Ethernet ports, and RAM. Diagnostic feedback and alarm statuses appear directly within the ToolboxST application.
