Working Principle
The KJ1501X1-BC1 receives 24 V DC input power and converts it into regulated backplane power for the DeltaV S-series carrier. The module distributes this power to installed controllers, I/O cards, and communication modules through the backplane. Status information is reported through the DeltaV backplane interface, and front-panel LEDs provide local indication. When two modules are installed in a redundant configuration, the system continues to operate if one module fails or is removed.
Installation Requirements
- Install only in a compatible DeltaV S-series carrier.
- Verify that the input power supply is 24 V DC and within the allowed range.
- Ensure the carrier is properly grounded according to Emerson installation guidelines.
- For redundant configurations, install two matching power modules in the designated slots.
- Confirm that the total backplane load does not exceed the supported capacity.
- Do not force the module into the carrier; align it with the guide rails and backplane connector.
- Verify LED status after power-up and check system diagnostics for fault messages.
Precautions for Use
- Do not connect field wiring directly to the power module.
- Verify input voltage polarity and range before energizing the system.
- Use redundant power modules where high availability is required.
- Replace failed modules only after confirming system hot-swap procedures.
- Monitor LED indicators and DeltaV diagnostics for early fault detection.
- Keep cabinet ventilation adequate to prevent overheating.
- For exact current rating, slot requirements, and redundancy rules, refer to the official Emerson DeltaV KJ1501X1-BC1 documentation.
