IS215GFOIH1AB GE

¥999.00

The GE IS215GFOIH1AB is a VMEbus terminal board manufactured by General Electric for the Mark VIe distributed control system (DCS). This board is a dedicated General-Purpose Fiber Optic Interface module, designed to provide high-speed, electrically isolated fiber optic communication for remote I/O, inter-rack data exchange, and communication with field devices in electrically noisy environments. The GE IS215GFOIH1AB combines the robust fiber optic capabilities of the “H1A” series with the “AB” suffix enhancements—typically indicating enhanced manufacturing quality, extended burn-in (96 hours), 100% X-ray/AOI inspection, and conformal coating as standard for maximum reliability in harsh environments. This board is designed for critical long-distance communication applications requiring absolute reliability.

  • Noise Immunity: Ideal for environments near VFDs, high-voltage equipment, and welding gear.

  • High-Speed Data Exchange: 10/100 Mbps supports real-time turbine control data.

  • Dual Redundant Ports: Two independent transceivers for redundancy.

  • Optical Link Quality Monitoring: Monitors signal strength for predictive maintenance.

  • Conformal Coating Standard: Protects against humidity, salt spray, and chemicals.

  • Extended Temperature Range: –25 °C to +70 °C.

  • Expanded Diagnostic Log: 750-event fault log.

  • Gold-Plated Connectors: Corrosion-resistant connections.

  • Hot-Swappable: No rack power-down for replacement.

  • Direct Retrofit: Replaces older GFOI series boards.

Application Fields

  • Remote I/O Racks: Communication between main control and remote cabinets

  • Field Device Communication: Connecting devices in electrically noisy environments

  • Inter-Rack Communication: Data exchange between multiple Mark VIe racks

  • Offshore platforms: Salt-spray environments requiring conformal coating

  • Compressor Stations: Communication near VFDs and high-power equipment

Selection Guidelines

  • When to choose: Critical long-distance fiber optic communication requiring environmental protection and expanded diagnostics.

  • When to choose “H1A” instead: For clean, controlled environments where conformal coating is not required.

  • Fiber Type: Multimode for distances up to 2 km; single-mode for up to 15 km.

  • Connector Type: Verify ST or SC connectors match field cabling.

  • Distance Verification: Ensure cable length does not exceed optical budget.

  • Coating Verification: Inspect under UV (365 nm) upon receipt.

  • Compatibility: Fits all Mark VIe VME64x racks. Requires ControlST v6.0 or higher.

Operational Precautions

  1. Fiber Handling: Avoid bending cables beyond minimum bend radius.

  2. Connector Cleaning: Clean connectors with approved tools before each connection.

  3. Optical Power Measurement: Verify power levels during commissioning.

  4. Link Quality Monitoring: Review signal trends in Toolbox ST.

  5. LED Diagnostics: Green = link/active; Amber = marginal signal; Red = link fault.

  6. Fault Log: Access 750-event log via Toolbox ST.

  7. Coating Care: Use GE-approved cleaner; inspect annually under UV.

  8. Hot-Swap: Remove/insert slowly under power.

  9. Spare Stock: Maintain 1 spare per 3–4 racks.

  10. ESD: Handle by edges with grounded wrist strap.

  11. Storage: Anti-static bag with desiccant at –40 to +85 °C; rotate every 3 years.
