Product Overview
The 1MRK002266-AAr00 is a plug-in binary input/output module developed for ABB Relion series protection and control IEDs. It acquires discrete status signals from circuit breakers, isolators and auxiliary switches, and executes contact output commands for trip circuits, alarm annunciation and interlock logic. This expansion hardware extends the native I/O capacity of protection relays, removing the need for external auxiliary relay panels in substation control schemes. Protection engineers, substation technicians and automation integrators rely on this module during new switchgear construction and legacy IED retrofit projects. Built-in signal filtering minimizes false status detections induced by electrical transients common within high-voltage substation environments.
Application Scenarios
- HV/MV Substation Feeder Protection IEDs: Collects breaker position, spring charged and isolator status signals; outputs trip and close commands to circuit breakers for feeder fault protection schemes.
- Power Transformer Protection Panels: Implements interlock logic for transformer tap changers, cooling fans and auxiliary alarm signalling, supporting comprehensive transformer supervision.
- Wind & Solar Farm Switchgear Control Cabinets: Interfaces switching equipment auxiliary contacts and drives local alarm indicators, ensuring reliable status reporting to substation SCADA systems.
- Industrial Medium Voltage Distribution Networks: Expands IED discrete signal capacity for motor protection and busbar protection schemes within factory power distribution systems.
