Overview
The ABB RXMM 1 RK 214 005-AN is an auxiliary relay module engineered for demanding applications in electrical control and protection systems. This compact, space-saving design integrates two independent relay coils with optimized contact arrangements, making it ideal for position repeat functions, interposing duties, and as an output relay in protective relay schemes.
Key Features
- Dual coil configuration with three contacts per coil
- Compact, space-saving design for switchboard and panel mounting
- DC-rated for stable operation in protection and control circuits
- Suitable for position repeat, interposing, and output relay applications
- High reliability in demanding industrial environments
Technical Specifications
The RXMM 1 module is constructed to meet rigorous industrial standards for auxiliary relay applications. Contact arrangements are optimized for control logic with minimal space requirements, supporting both heavy-duty and standard switching operations.
Typical Applications
- Protection relay schemes and trip logic circuits
- Position repeat functions in electrical switchgear
- Interposing relay modules in control equipment
- Output relay in numeric and digital protective relays
- Auxiliary relay logic in substations and control panels
Compatibility & Replacements
The RXMM 1 is widely recognized in electrical power systems as a standard auxiliary relay module. Modern replacements such as the RXMC 1 offer pin-compatible configurations with improved operating speeds, though operating time specifications should be verified for direct substitution in existing applications.
