Features:
- Twelve discrete output channels with individual front-panel status indication.
- Dual IONet Ethernet interfaces for connection to the Mark VIeS control network.
- Documented for compatible TRLYS relay terminal-board executions.
The IS220YDOAS1AJ is designed as the field-facing output I/O pack within a qualified GE Mark VIeS installation. It receives output commands over IONet and applies them through the paired relay terminal board, while the twelve numbered faceplate indicators provide immediate channel-state visibility during operation and troubleshooting.
Replacement approval should be based on the complete AJ suffix, the installed TRLYS terminal-board execution and the project configuration. Before removal, record the module label, installed position, Ethernet connections, terminal-board part number and channel allocation. After installation, verify power and network diagnostics and prove each affected output under the site commissioning procedure.
The IS220YDOAS1AJ General Electric Mark VIeS Discrete Output Module is listed as Active / Available from OEM. Exact revision, condition and supplied scope are confirmed in the written quotation.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
IS220YDOAS1AJ is used for discrete output duties in qualified GE Mark VIeS turbine-control projects, including relay-driven actuators, alarms and auxiliary equipment. The actual field load and interposing relay arrangement must match the installed TRLYS terminal board and project drawings.
Typical installations include power-generation turbine packages, turbine-driven compressor trains and industrial utility systems. Industry context does not establish interchangeability; approve the module by its complete suffix and system documentation.
The matching IS220YDOAS1AJ label states 28 Vdc, 0.71 A dc module power, 30 Vdc, 5 A dc contact output and an ambient range of -30 to +65 degrees C. The faceplate includes twelve numbered output indicators, ENET1 and ENET2 IONet ports and an infrared service port.
GE family documentation lists IS200TRLYS1F, IS200TRLYS2F, IS400TRLYS1F and IS400TRLYS2F as associated relay terminal-board executions. Confirm the exact installed board revision before replacement.
Before removal, photograph the complete IS220YDOAS1AJ label and record the installed position, terminal-board part number, channel allocation, Ethernet connections and active diagnostics. Preserve the controller and I/O configuration in accordance with the site procedure.
After installation, confirm module power, both IONet links and controller diagnostics, then prove every affected output in a safe test state. Do not assume that another YDOA or PDOA suffix is a direct substitute.
