Product Overview
The ABB 1MRK002246-BB is a highly reliable binary input/output module, tailored for use in demanding industrial and power automation environments. This module integrates both input and output binary functions in a single unit, allowing it to monitor discrete signals from field devices and simultaneously control actuators such as relays, alarms, and circuit breakers.
It is especially well-suited for substations operating under the IEC 61850 standard and is typically integrated within ABB’s advanced protection and control systems. The compact yet rugged design makes it a practical solution for space-constrained switchgear panels or automation cabinets, while its versatile features provide system integrators and engineers with high configurability and interoperability.
