Description
The ABB 1MRK002247-AGr02 is a Transformer Input Module (TRM) associated with ABB Relion 670-series protection and control equipment. The 1MRK 002 247 family is used for analog current and voltage transformer inputs, with configurations including 6I + 6V and other CT/VT combinations depending on the exact suffix and system configuration. ABB documentation identifies this part family as a Transformer Input Module for Relion protection applications.
This module is intended for integration with protection, measurement, and control systems in substations and power-generation installations. It provides the interface between external CT/VT secondary circuits and the host protection IED. The exact input configuration and terminal arrangement should be confirmed from the module nameplate and the host IED configuration before replacement.

⚙️ Application
The 1MRK 002 247 transformer-input family is used in ABB Relion protection platforms including RED670 and other 670-series applications. Available configurations vary by suffix; ABB documentation lists versions with different combinations of current and voltage inputs, including 6I + 6V at 1A or 5A and other CT/VT arrangements.
Typical applications include:
- Substation protection systems
- Line and busbar protection
- Transformer protection
- CT/VT signal acquisition
- Power-system measurement
- Replacement of an existing ABB TRM with the same ordering code
⚠️ Replacement Note: The suffix AGr02 is important. Do not substitute another 1MRK 002 247 variant solely because the base part number matches. Verify CT secondary rating, VT inputs, terminal type, wiring, and host IED configuration before installation.
