IS200VCCCH1D | GE Electric 6-slot VME backboard chassis
Product Function
The IS200VCCCH1D is a 6-slot VME backplane chassis designed for GE’s Mark VIe turbine control systems. It provides power distribution, cooling, and high-speed communication infrastructure for redundant controller modules (e.g., IS420UCSBH1A) and I/O packs, enabling robust industrial-grade control of critical turbomachinery.

Technical Notes
- 🛠️ Configuration:
- Slot 1-2: Controller modules (e.g., IS420UCSBH1A)
- Slot 3-5: I/O packs (e.g., IS420PDIAH1A)
- Slot 6: Power module (e.g., IS420EPDMG3A)
- 🔌 Wiring:
- TB1/TB2: Field wiring terminals (removable)
- P1/P2: Fiber-optic SER links for rack-to-rack comms
- ⚡ Power Safety:
- Overcurrent trip at 120% rated load
- Ground-fault monitoring (>5mA)
- 📶 Status Indicators:
- Green LED: Healthy voltage per slot
- Amber LED: Fan/Power warning
- Red LED: Critical failure (e.g., overtemp)
Integration Rules:
- Max. 4 chassis per SER fiber loop (≤100m distance).
- Requires GE’s ToolboxST™ for backplane diagnostics.
- Annual maintenance: Fan cleaning, contact reseating.
