Frequently Asked Questions (FAQ)

1. What role does the IS200CABPG1B play in the Mark VI system?

It serves as a backplane for interconnecting control modules, enabling signal routing, power distribution, and communication between key components in the GE Mark VI control system.

2. Is this board an active processing unit?

No. The IS200CABPG1B is a passive board. It does not perform data processing but provides the essential interface structure for other active modules.

3. How is the board typically installed in the system rack?

It is mounted at the rear of a control chassis or cabinet, where it supports vertical module insertion through card-edge connectors, secured by screws or rail guides.

4. Can the IS200CABPG1B be reused with newer control modules?

Yes, as long as the new modules remain electrically and mechanically compatible with the existing backplane design, the board can be retained during system upgrades.

5. What signs might indicate a backplane board issue?

Frequent module communication errors, system boot failures, or physical damage to connectors may indicate the backplane requires inspection or replacement.

6. Does this board require firmware updates?

No. The IS200CABPG1B has no onboard firmware. All software logic resides in the connected control modules.

7. In what environments is this board typically used?

It’s primarily used in gas and steam turbine control systems, substations, and other heavy industrial automation systems where reliability and high uptime are critical.

8. How is electrical isolation handled on this board?

The board follows GE’s strict design practices, including segmented ground planes and shielding for EMI suppression, though isolation components are generally located on the connected modules.

9. What materials is the board constructed from?

It uses multilayer industrial-grade PCB material, with plated through-holes and high-density connectors designed to endure thermal and mechanical stress.

10. How long does a typical IS200CABPG1B board last in operation?

When installed in a clean, temperature-controlled cabinet, it often operates reliably for 10 to 15 years or more without needing replacement.
