Description
Product Description
The IS215ISBBH2A is a General Electric Mark VI Splitter Communication Switch used in the Speedtronic turbine control communication architecture. The ISBB is a compact standalone communication module rather than a conventional VME rack card. It provides a three-port Ethernet communication interface for distributing and routing communication paths within the Mark VI network. The H2A version uses ports identified by function, including Full Duplex, Transmit Out, and Receive In, and includes a Receiver Active diagnostic indicator. The module is designed for DIN-rail mounting and uses a 24 VDC control-power input.

Functional Features
- Provides communication-splitting functionality within compatible GE Mark VI control architectures.
- Three Ethernet ports provide dedicated communication paths for the associated network connections.
- Port labeling identifies the Full Duplex, Transmit Out, and Receive In functions.
- The Receiver Active LED provides a quick indication of incoming communication activity.
- Compact standalone construction allows installation within the Mark VI control cabinet.
- DIN-rail mounting supports cabinet-level installation.
- The ventilated metal enclosure is designed for industrial control cabinet applications.
- Uses a 24 VDC power input for operation.
- The H2A hardware version should be matched carefully because ISBB variants such as H1A and H2A should not automatically be considered interchangeable.
FAQ
Q: What is the IS215ISBBH2A used for?
A: It is a Mark VI Splitter Communication Switch used to distribute communication signals within compatible GE turbine control networks.
Q: How many Ethernet ports does it have?
A: The H2A version has three Ethernet ports with dedicated communication functions.
Q: What does the Receiver Active LED indicate?
A: It provides an indication of upstream communication activity. If the indicator is off, the upstream cable or transmitting device should be checked before assuming the splitter itself has failed.
Q: Does the IS215ISBBH2A use a VME rack slot?
A: No. It is a standalone communication module rather than a conventional plug-in VME board.
Q: What power supply does it require?
A: Available technical references identify a 24 VDC control-power input.
Q: Is IS215ISBBH2A interchangeable with IS215ISBBH1A?
A: Interchangeability should not be assumed. The H1A and H2A are distinct hardware variants. Match the complete part number, network arrangement, connectors, and system documentation before replacement.
Troubleshooting & Safety
- Confirm the complete IS215ISBBH2A part number and hardware revision before installation.
- Check the Receiver Active LED before replacing the module.
- Inspect the upstream Ethernet cable and all three communication connections for loose or damaged connectors.
- Verify that the upstream Mark VI communication device is operating normally.
- Confirm the 24 VDC supply and polarity before powering the module.
- Check the correct port assignment for Full Duplex, Transmit Out, and Receive In connections.
- Do not assume a network communication failure is caused by the splitter; controller, VCMI, cable, I/O network, or configuration faults can produce similar symptoms.
- Disconnect power before removing or installing the module.
- Follow site lockout/tagout and electrical safety procedures when working inside the Mark VI control cabinet.
- Verify the exact hardware variant and network configuration before commissioning a replacement.
