The IS200ISBEH2A serves as a communication interface within the ISbus network, allowing for the extension of the bus to connect additional modules or devices. It interfaces directly with the J11A local ISBus Interface Connector on the Control Assembly Backplane (IS200CABP). The module's design includes:
Fiber-optic communication: Utilizes fiber-optic connectors for high-speed data transmission, ensuring minimal electromagnetic interference.
Power conversion: The onboard DC/DC converter steps down the input voltage to provide a stable 5V output, powering the module and connected devices.
Status indicators: LEDs provide real-time status information, aiding in diagnostics and system monitoring.
Interlock bypass: The jumper switch allows for interlock bypassing during maintenance or troubleshooting procedures.
The IS200ISBEH2A is integral to the EX2100 excitation control system, which is part of the broader Mark VI turbine control platform. Its primary applications include:
Expanding ISbus networks: Facilitates the addition of modules or devices to the ISbus network.
System upgrades: Enables the integration of newer modules into existing systems.
Maintenance and diagnostics: Assists in system monitoring and troubleshooting by providing clear status indicators.
The IS200ISBEH2A is available from various suppliers, with options for both new and refurbished units. For instance:
Automation Industrial offers new surplus units with a 1-year warranty
AX Control provides in-stock units with a 3-year warranty and repair services
World of Controls lists both unused and rebuilt units, with same-day shipping available
