Overview
The ABB RXMA2RK211185-AD is an auxiliary contact module engineered for the RXMA 2 relay platform. As part of ABB’s established line of auxiliary signalling and tripping relays, this contact block extends the functionality of base relay units by adding dedicated switching contacts. The modular design allows engineers to configure contact logic precisely for control and protection applications without replacing the primary relay.

Compatibility & Replacements
This module is compatible with ABB RXMA 2 relay base units. When sourcing replacements, confirm the contact configuration (RK 211) and voltage rating (185-AD variant) match your system requirements. ABB relay modules are typically non-interchangeable between different relay series; verify base unit compatibility before ordering. For alternative contact configurations within the RXMA 2 family, contact your ABB distributor or consult the relay system documentation.
