Product Description

GE IS215VCMIH2BB & IS200VCMIH2BCC | VME Communication Interface Board (VCMI) for Mark VI Turbine Control

VMEbus master controller & IONet/ONet communication hub with dual-port RAM, 3 ONet ports, and 1 serial port for gas/steam turbine & generator control systems

1. Product Overview

The GE IS215VCMIH2BB (for Mark V upgrades) and IS200VCMIH2BCC (Mark VI standard) are VCMI (VME Communication Interface) boards, which are core communication components in GE Speedtronic Mark VI turbine control systems, and also applicable to Mark V gas turbine retrofits. As VMEbus master controllers and bus arbitrators, they provide a high - speed data exchange bridge between the VMEbus backplane, IONet/ONet field networks, and system controllers, supporting multi - processor parallel operation through dual - port RAM (256 KB) to VMEbus, and enabling seamless data sharing between CPUs and I/O modules. The front panel is equipped with 3 ONet (IONet) ports (10 Mbps, fiber - optic/electrical) and 1 RS - 232 serial port (for configuration/debugging), supporting redundant network topology, with an ONet communication distance of up to 1 km (electrical) and 20 km (single - mode fiber). It has a 32 - bit VMEbus interface (64 MB address space), a 25 MHz clock, 512 KB Flash memory, and 2 MB DRAM, and is equipped with 8 - channel digital status input/output for system monitoring. With a redundant dual - power supply of +5 V DC (3 A) and ±12 V DC (0.8 A), reverse connection protection, 4000 V ESD protection, and a working temperature range of - 40°C to +70°C, it is very suitable for critical control scenarios such as power generation, oil & gas, and petrochemical industries, ensuring the reliable operation of turbine speed regulation, load distribution, and safety protection systems.

4. Installation & Maintenance

Installation: Insert into Mark VI VME chassis Slot (VCMI designated); connect 3 ONet ports to IONet ring/dual network; link RS-232 to configuration PC; wire redundant +5 V/±12 V power; set VME address via DIP switches; power on and verify bus arbitration & ONet communication.

Maintenance: Weekly: Check status LEDs (Power, VME Bus, ONet 1-3, Fault); Monthly: Verify VME data transfer and ONet port signal quality; Annual: Test dual-port RAM integrity and firmware update; clean module contacts and inspect power/reverse protection.

Safety Notes: Power off chassis before insertion/removal; use shielded cables for ONet/RS-232; ensure proper grounding for EMC compliance; avoid hot-swapping to prevent VMEbus damage.
