General Electric IS220YDOAS1AJ Mark VIe Discrete Output Pack

Description

The IS220YDOAS1AJ is a discrete output pack engineered for the Mark VIe series control platforms. This device forms an electrical interface linking one or two redundant I/O Ethernet networks directly to a discrete output terminal board. It runs dedicated firmware to regulate up to twelve external potential relays while processing real-time relay and fuse feedback monitoring tracking loops. Equipped with an internal acquisition board and a specialized BPPB common processor board, the hardware uses a DC-37 pin connection system to drive terminal components. The control system supports flexible hardware redundancy profiles, including three modules for Triple Modular Redundant (TMR) voting applications or a single module for simplex configurations, managing diagnostic checks via voting disagreement algorithms.

Features

• Provides electrical control interface functions between I/O dual Ethernet networks and external discrete output hardware.
• Drives up to twelve potential relays with dedicated relay and fuse feedback diagnostic monitoring loops.
• Utilizes a specialized voting disagreement methodology with enablement configurations to pinpoint network faults.
• Runs internal automated self-diagnostic cycles upon initialization to check flash memory, processor board circuits, RAM, and active dual Ethernet ports.

Applications

• Mark VIe Distributed Control Systems: Driving field relays and handling discrete control sequencing across turbine automation nodes.
• TMR Redundant Control Loops: Providing synchronized tri-modular processing for high-availability industrial systems.
• Simplex Output Interfaces: Direct discrete terminal board switching setups inside non-redundant utility panels.

Installation Guidelines

• Disconnect all control power lines before fitting the discrete output hardware to the terminal base block.
• Secure the DC-37 pin connection point tightly to maintain error-free electrical path linking to the field relays.
• Configure the correct application architecture within the ControlST Software Suite (Simplex or TMR) before online deployment.
• Ensure adequate ventilation spacing to maintain the ambient operating thermal metrics between -30 and + 65 Celsius.
