ABB 1MRK002239-BBr01 Modul napájecího zdroje skladem

Configured to provide regulated auxiliary power within ABB Relion 670 series protection and control IEDs, the ABB 1MRK002239-BBR01 (1MRK002239 Power Supply Module) supplies a regulated 24 VDC internal system bus output from the specified DC input ranges. The module is associated with SR91C790 hardware and rack-mounted protection equipment.

Hardware Specifications

ABB Relion 670 Power Supply Interface

The 1MRK002239-BBR01 functions as a power conversion and distribution component rather than a field communication module. Its regulated 24 VDC output supplies the internal system bus and associated protection, logic, and I/O hardware. The supplied input ranges indicate that the applicable input configuration must be verified against the installed sub-hardware before energization.

No Profinet or EtherNet/IP communication function is specified for this power supply module. Firmware, network protocol, and I/O communication functions should therefore be attributed to the corresponding Relion 670 hardware rather than to the power supply itself.

Frequently Asked Questions

Q: What output voltage does the 1MRK002239-BBR01 provide?
A: The supplied data specifies a regulated 24 VDC output for the internal system bus.

Q: What input voltage ranges are specified for this module?
A: The supplied data lists 90 - 250 VDC and 18 - 36 VDC, with the applicable range depending on the sub-hardware configuration.

Q: Does the module provide Profinet or EtherNet/IP communication?
A: No communication function is specified for the power supply module. It is identified as a power conversion and internal system bus supply component.

Field Installation Guidelines

Verify the installed module designation and applicable input voltage range before energization. Confirm that the rack chassis and connector arrangement correspond to the intended Relion 670 hardware configuration.

Route power wiring separately from high-level signal and communication wiring where practical. Maintain appropriate separation from switching and high-current conductors to limit conducted and radiated electrical interference.

Connect protective and functional grounding according to the equipment chassis and site grounding scheme. Do not use signal cable shields as substitutes for protective grounding conductors.

Before insertion or removal, follow the equipment manufacturer's specified power isolation procedure. Do not assume hot-swap capability unless it is explicitly supported by the applicable Relion 670 hardware documentation.
