Features:
- Twenty-four discrete contact inputs with individual front-panel status indication.
- Dual IONet Ethernet interfaces for connection to the Mark VIeS control network.
- Documented for compatible STCIS and TBCIS terminal-board executions.
The IS220YDIAS1AK is designed as the field-facing contact input I/O pack within a qualified GE Mark VIeS installation. It acquires twenty-four discrete field states through the paired terminal board, while the numbered faceplate indicators provide immediate input-state visibility during operation and troubleshooting.
Replacement approval should be based on the complete AK suffix, the installed STCIS or TBCIS execution, the contact-wetting design and the project configuration. Before removal, record the module label, installed position, Ethernet connections, terminal-board part number and input map. After installation, verify power and network diagnostics and prove every affected contact state under the site commissioning procedure.
The IS220YDIAS1AK General Electric Mark VIeS Discrete Input 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.
IS220YDIAS1AK is used for discrete contact monitoring in qualified GE Mark VIeS turbine-control projects, including limit switches, auxiliary contacts, permissives and equipment status signals. The actual wetting source and field circuit must match the installed STCIS or TBCIS 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 IS220YDIAS1AK label states 28 Vdc, 0.24 A dc module power, 0 to 32 Vdc contact input, 32 Vdc, 110 mA dc contact-wetting output and an ambient range of -30 to +65 degrees C. The faceplate includes twenty-four numbered input indicators, ENET1 and ENET2 IONet ports and an infrared service port.
GE family documentation lists IS200STCIS1A, IS200STCIS2A, IS400STCIS1A, IS400STCIS2A, IS200TBCIS2C and IS400TBCIS2C terminal-board executions. Confirm the exact installed board revision and wetting arrangement before replacement.
Before removal, photograph the complete IS220YDIAS1AK label and record the installed position, terminal-board part number, input map, wetting source, 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 the open and closed state of every affected input. Do not assume that another YDIA or PDIA suffix is a direct substitute.
