ABB 1MRK002252-DA Universal Backplane Module (UBM)

FAQ

Q1: What is the ABB 1MRK002252-DA used for?
The ABB 1MRK002252-DA is a Universal Backplane Module (UBM) used in ABB Relion protection and control systems. It provides the internal connection platform for multiple relay modules and ensures reliable signal transmission between hardware components.

Q2: What is the difference between 1MRK002252-CA and 1MRK002252-DA?
The main difference is the supported module configuration. The 1MRK002252-CA is configured for 1 ADM + 1 TRM, while the 1MRK002252-DA supports 2 ADM + 2 TRM modules, providing a larger I/O capacity.

Q3: Which ABB systems are compatible with the 1MRK002252-DA?
The module is designed for ABB Relion 670 series protection and control IED systems where a UBM configuration with multiple ADM and TRM modules is required.

Q4: What are the dimensions and weight of the ABB 1MRK002252-DA?
The module has approximate dimensions of 150 × 130 × 35 mm and weighs approximately 0.10 kg.

Q5: What is the main function of a Universal Backplane Module (UBM)?
The UBM provides mechanical mounting and electrical interconnection between relay modules, allowing different protection, measurement, and communication boards to work together as an integrated system.

Q6: Can the ABB 1MRK002252-DA replace an existing UBM module?
Yes. It can be used as a replacement when the existing protection relay configuration requires the same UBM model and supports the same module arrangement.

Q7: What should be checked before installing the ABB 1MRK002252-DA?
Before installation, verify the relay model, supported ADM/TRM configuration, hardware revision, connector condition, and compatibility with the existing protection system.

Q8: What are the advantages of the ABB 1MRK002252-DA?
The module provides reliable internal connections, flexible hardware expansion, compact design, and stable performance for ABB protection and substation automation applications.
