ABB Relion IRIG-B Time Synchronization

The module decodes external IRIG-B time codes and converts received timing information into an IED system time reference.
It supports IRIG-B formats 001, 002, and 100 according to the supplied technical information.
The input interface may use a BNC coaxial connection or optocoupler input, depending on backplane configuration.
The 24 V DC operating supply is provided through the IED backplane rather than a separate field supply.
For firmware maintenance, compatibility should be checked against the installed Relion IED hardware and applicable software release.

Frequently Asked Questions (FAQ)

Q: What signal does the 1MRK002305-AAr01 process?
A: It processes IRIG-B time-code signals supplied by an external master clock or GPS-based timing source.

Q: How is the module powered inside the IED?
A: The supplied data specifies a 24 V DC operating supply delivered through the IED backplane.

Q: Can the module be installed as an external standalone timing device?
A: The supplied data identifies it as hardware for ABB Relion 670/650 IEDs, with IP20 protection when installed inside the IED rack enclosure.

Field Installation Guidelines

Install the module only in the specified ABB Relion IED hardware configuration and compatible backplane position.
Verify the installed IED type, module position, connector arrangement, and applicable ABB hardware documentation before energization.
Route IRIG-B coaxial wiring separately from high-voltage, switching, and high-current conductors where practical.
Maintain proper cable shielding and terminate the shield according to the installed IED grounding scheme.
Avoid ground loops when connecting the external master clock or GPS receiver to the IED timing input.
Confirm the IRIG-B source format before commissioning, particularly when multiple time-code formats are available.
Verify the received time reference after installation using the IED diagnostic or time-synchronization status functions.
Do not assume compatibility from the part number alone when replacing modules across different Relion hardware revisions.
