DESCRIPTION

The General Electric IS415UCVHH1A is a controller board manufactured by General Electric as part of their Mark VIe series VME platforms, specifically designed for gas turbine control systems. This 6U high single board computer (SBC) operates the turbine application code and connects to turbine I/O boards via the VME bus, mounted on a VME rack known as the control module. It runs on the QNX real-time, multitasking operating system, renowned for its speed and reliability in industrial applications.

Connectivity and Interfaces

The IS415UCVHH1A provides connectivity through three communication ports:

• Ethernet for HMI and control equipment communication (UDH).
• RS-232C port (COM1) for setup connections.
• RS-232C port (COM2) for communication with distributed control systems (DCS).

Operation

This controller is optimized for steam, gas, land-marine derivative (LM), or balance of plant (BOP) applications. It can execute up to 100,000 rungs or blocks per second under normal conditions.

Synchronization and Data Handling

• Synchronizes to the VCMI communication board's clock within 100 microseconds.
• Uses the VME bus to exchange data with the control system database (CSDB) via the VCMI board.

Installation

The IS415UCVHH1A, along with a VCMI board, forms a control module. It fits into various rack types:

• GE Fanuc integrator's rack for standalone modules with remote I/O.
• Mark VIe racks for both local and remote I/O configurations.
