About the IS220YDOAS1A

The IS220YDOAS1A is a Discrete Output Pack from the Mark VIe Series. This module was manufactured by GE Energy. The IS220YDOAS1A acts as an electrical interface between one or two I/O Ethernet networks and a discrete output terminal board. 

IS220YDOAS1A Hardware Tips and Specifications

The main components of the IS220YDOAS1A are an acquisition board and a common processor board. One key feature of this pack is its ability to control up to twelve potential relays as well as accept specific feedback from terminal boards. The output from this pack will be provided through a DC-37 pin connector which will connect directly with the associated terminal board.

This pack can be used in two different redundancy configurations. If the IS220YDOAS1A pack is being used in a TMR redundant application three I/O packs are required. Only one pack is required when being used in a simplex application. 

This pack has the ability to perform self-diagnostic tests, and one of these tests is a power-up test that will check the following features:

• Processor board hardware
• Flash memory
• Ethernet ports
• RAM

All of the details for this diagnostic will be available within the ToolboxST application of the YDOA pack. The YDOA pack has twelve LEDs that can indicate status. The IS220YDOAS1A also has specific alarms which will indicate a variety of potential errors.
