IS215VCMIH2C GE Mark VI

The IS215VCMIH2C is a VME Communication Interface Card (VME CIC) specifically designed for the GE Mark VI gas turbine control system. The Mark VI is an advanced turbine control system developed by General Electric (GE) as part of the Speedtronic series, widely used in the control of power plants equipped with gas and steam turbines. It serves as a critical communication component within the Mark VI control system.

It features a standard 6U-high VME board design with a width of 0.787 inches, enabling seamless integration into standard VME chassis and ensuring system modularity and scalability. It not only enables data exchange between I/O cards and other I/O cards mounted on the VME backplane but also connects I/O modules, I/O backup protection modules, and triple-redundant control modules on expansion racks.

Additionally, this card serves as the communication interface for the system control network (IONet), ensuring that control commands and field data are transmitted efficiently and accurately throughout the network infrastructure.

A chemical company upgraded the steam turbine control system in its power plant by implementing the GE IS215VCMIH2C. Since the new system went into operation, it has not only enabled smoother speed control and faster startup times, but its robust data logging capabilities have also successfully helped analyze and optimize steam consumption, resulting in an overall energy efficiency improvement of approximately 2%.

Similar/Upgrade Models: IS215VCMIH2B, IS215VCMIH2CA, IS215VCMIH2CC. These models are largely compatible in terms of pinout and functionality, but may have minor differences in flash memory capacity, number of IONet ports, or processor version.

• Main Processor Modules: Mark VI controllers such as UCVE and UCVX
• I/O Boards: Various Mark VI analog/digital I/O boards (e.g., TCQA, STCA, etc.)
• Terminal Boards: TBQA, TBQC, etc., used for field signal input and conditioning
• Power Supply Modules: PS modules that provide stable power to the VME rack

The "Fail" indicator on the IS215VCMIH2C panel is lit. What should I do?

First, check whether the rack power supplies (+5V, 12V, 15V, 28V) are within the normal range. If the power supplies are normal, try pressing the Reset button to restart the card. If the problem persists, it may be due to hardware damage, and a replacement part will be required.

Does the IS215VCMIH2C support hot-swapping?

Yes. The module can be replaced while the system is running, without the need to shut down.

Which gas turbine models is the IS215VCMIH2C compatible with?

The Mark VI series supports common gas turbine units such as Frame 5, 7, 9, and 9HA.
