GE Mark VI IS215ISBBH2A Communication Diversion Switching Module
GE IS215ISBBH2A (ISBB) is a dedicated communication diversion switching module for the Speedtronic Mark VI gas turbine control system. IS215ISBBH2A is mainly used for Ethernet signal distribution and bypass switching in gas turbine control networks, including three dedicated Ethernet ports: full duplex input port, transmission output port, and reception input port. It is responsible for diverting and forwarding upstream control communication signals, and supports communication link bypass mode; IS215ISBBH2A can monitor the upstream link signal status in real time, ensuring high-speed real-time communication between Mark VI controllers and between controllers and I/O cards. When the link is abnormal, it provides status indication and is a dedicated signal distribution and link diagnostic component in the gas turbine main control network.

Main product range
- Control system (DCS/PLC/CNC): panel controller, HMI and human-machine interface, industrial PC, CPU processor module, communication module, analog/digital I/O module
- Drive and motion control: frequency converter, servo drive, servo motor, power module
- Robot spare parts: key spare parts such as robot control board, axis computer, servo unit, I/O module, etc
- State monitoring and safety system: vibration monitoring system, safety instrumented system (SIS), redundant controller
Application Industry
The products are widely used in various industrial fields such as metallurgy, oil and gas, petrochemicals, electricity, power transmission and distribution, water conservancy, water treatment and environmental protection, coal mining, aluminum industry, glass manufacturing, paper and printing, textile printing and dyeing, machinery manufacturing, electronics manufacturing, automobile manufacturing, plastic machinery, boiler heating, energy, etc.
GE Mark VI IS215ISBBH2A Communication Diversion Switching Module
Product Features
- Customized specifically for GE Mark VI gas turbine systems, not a universal switch, following the Mark VI private control communication protocol to achieve real-time control signal diversion and bypass.
- The three ports have clear division of labor, independent transmission and reception links, support communication bypass switching, facilitate online maintenance and replacement of downstream equipment without interrupting the main link.
- Single channel receiving status indicator light, quickly determine whether the upstream communication link is normal, whether the cable is disconnected, and the fault location is simple and intuitive.
- The shell is equipped with a ventilation and heat dissipation structure, suitable for long-term continuous operation inside the cabinet. The metal shell is resistant to electromagnetic interference and suitable for strong electromagnetic environments between gas turbines.
- DIN rail installation, easy disassembly and assembly, suitable for standard installation layout of control cabinets.
- Equipped with link failure monitoring capability, the indicator light will turn off when the upstream signal is lost, providing early warning of communication failures.
- Highly reliable industrial grade design, capable of withstanding power plant vibrations, temperature and humidity fluctuations, and meeting the high availability requirements for turbine unit control.
