The GE IS215VCMIH2C (and revision IS215VCMIH2CC) is a 6U VME Bus Master Controller Board manufactured for Speedtronic Mark VI turbine control systems. It serves as the master bus controller for control racks and remote I/O racks, managing high-speed deterministic IONet data distribution across R, S, and T channels.
Technical Specifications
Form Factor: Standard 6U VMEbus card (233.35 mm x 160 mm)
Bus Architecture: 32-bit VMEbus Master Controller
Power Supply Requirement: +5 VDC from VME backplane (< 15 W draw)
IONet Ports: 3 optical/coaxial IONet channels for R, S, and T redundancy
Frame Rate Execution: 10 ms control loop frame rate
Operating Temperature: 0°C to +60°C
Key Features & Applications
The VCMI card acts as the central communication hub within Mark VI control architectures:
Board ID Management: Scans and identifies all electronic boards and terminal boards connected within the VME rack frame.
Triple Modular Redundancy (TMR): Synchronizes data communications across isolated R, S, and T channels to maintain voting integrity.
Dual-Port Memory Interface: Enables real-time dual-port memory transfers between controller processors and field I/O modules.
Installation Guide
ESD Precautions: Wear an anti-static wrist strap when handling the VME circuit board.
Rack Insertion: Align the card edge guides into Slot 1 of the 6U VME rack frame and press firmly to seat backplane connectors.
Retaining Screws: Tighten top and bottom front-panel retaining thumb screws to lock the board in place.
Cabling: Connect IONet communication cables to the designated R, S, and T front ports.
Selection Tips
Rack Placement: The VCMI must always reside in Slot 1 of the VME rack to act as bus master.
Revision Matching: Confirm whether your system requires coaxial or fiber optic IONet front interfaces (H2C vs H1A series).
