PRODUCT INFORMATION
Product Overview
The General Electric IS215VCMIH2B is a VME bus master controller board. It operates within the Speedtronic Mark VI turbine control system architecture. This module interfaces high-speed communication between the main controller and distributed I/O boards. The unit also assigns and manages rack board identifiers and terminal board addresses. It supports turbine control systems for gas, steam, and wind applications.
The board features an onboard Texas Instruments 32-bit digital signal processor. It includes 256k by 32 SRAM for high-speed data transfer configuration. The assembly is built as a single-slot 6U high VME form factor board. A protective conformal coating shields internal board components from harsh operating environments. This specific hardware represents functional revision B within the VCMI Group 2 series.
