FAQ

1. What voltage range is supported by the 8U-BXCB20-CN module?

   The module supports 24VDC and 48VDC input voltage configurations, depending on system setup.

2. Is each breaker channel independently isolated?

   Yes, each of the 20 breaker positions offers individual galvanic isolation and overcurrent protection.

3. Can the breaker modules be replaced individually?

   Yes, the plug-in design allows for individual breaker replacement without disturbing other circuits.

4. What is the default rated current per breaker?

   The default is 6A per channel, but this can be adjusted by selecting different breaker ratings.

5. Does the module provide short-circuit protection?

   Yes, thermal-magnetic breakers protect against both overload and short-circuit conditions.

6. Can the module be used outside Honeywell systems?

   While optimized for Honeywell systems, it can be adapted for other industrial automation environments that use 24/48VDC control power.

7. Is the module hot-swappable?

   The breakers themselves can be serviced with proper precautions, but full hot-swapping of the assembly is not recommended under load.

8. How are diagnostics communicated to the control system?

   Local LED indicators provide visual diagnostics; some configurations can include auxiliary signaling for system integration.

9. What is the thermal dissipation of the module during operation?

   Thermal dissipation depends on load; passive cooling is sufficient for most installations within spec.

10. Does it require any software configuration?

    No software configuration is necessary; the module operates as a passive hardware power distribution system.
