The IS220YDOAS1A is a safety-certified discrete output module developed by General Electric for the Mark VIeS functional safety control system series. Functioning as a high-integrity Safety Discrete Output I/O Pack, the device establishes an intelligent electrical interface between redundant Ethernet control networks and discrete output terminal boards. It receives digital commands from the safety controller over dual communication channels and transforms them into physical control states to drive external field components such as solenoids, contactors, and interlock relays. Engineered for critical infrastructure and turbine protection loops, the module supports single, dual, or Triple Modular Redundant (TMR) structural layouts to ensure maximum fault tolerance and system availability in high-risk operational environments.
| Parameter Classification | Specification Detail |
|---|---|
| Manufacturer | General Electric (GE) |
| Model Number | IS220YDOAS1A |
| Product Series | Mark VIeS Control System |
| Module Type | Safety Discrete Output I/O Pack |
| Country of Origin | USA |
| Minimum Supply Voltage | 27.4 V dc |
| Nominal Supply Voltage | 28.0 V dc |
| Maximum Supply Voltage | 28.6 V dc |
| Maximum Current Consumption | 0.71 A dc |
| Network Interfaces | Dual 10/100 Base-T Ethernet ports (ENET1 / ENET2) |
| On-Board Diagnostics | 18 Status LED Indicators |
| Operating Temperature Range | -30 degC to +65 degC |
| Physical Weight | 0.68 kg |
| Dimensions | 16.0 cm x 16.0 cm x 12.0 cm |
| Connector / Interface | Function |
|---|---|
| DC-37 Pin Plug | High-density connector delivering electrical output control signals and diagnostics to the terminal board |
| ENET1 | Primary RJ45 network port linking the module to the safety network infrastructure |
| ENET2 | Secondary RJ45 network port providing parallel data path redundancy to the backup controller |
| Power Socket | Side-mounted input port accepting local power supply connections with built-in surge limiting |
| Ground Bolt | Dedicated physical chassis point for system noise containment and shielding drain termination |
Secure the corresponding discrete output terminal board firmly to the cabinet subpanel or DIN rail mounting grid. Align the rear DC-37 pin connector of the module with the receptor plug on the terminal board base. Press the module down vertically until the contact seating is secure, and tighten the mechanical retaining fasteners onto the mounting plate to prevent high-frequency mechanical loosening.
Connect individual twisted-pair industrial Ethernet lines to the ENET1 and ENET2 RJ45 communication ports. To establish a fault-resilient dual-bus topology, route the cables through separate wireways within the panel enclosure to reduce cross-coupling and eliminate localized points of failure across independent network layers.
The module includes built-in inrush-limiting components on its internal power rails, allowing maintenance technicians to disconnect or insert the module while the system terminal boards are energized. When replacing a device under live conditions, disconnect the redundant network communication links and the side-mounted power supply input block prior to mechanical disengagement from the board.
