The ABB 1MRK002266-AAr00 Digital Input/Output Module delivers enterprise-grade binary signal acquisition and control capabilities specifically designed for integration with ABB Relion series protection relays and substation automation architectures. This industrial-hardened module combines high-density I/O channels with robust galvanic isolation, enabling reliable operation in electrically demanding power distribution and transmission environments.
Distinctive Product Characteristics
- High-Density I/O Architecture: 16 isolated digital inputs and 8 relay contact outputs in a compact DIN-rail mountable form factor
- Wide Input Voltage Range: 18-60V DC input acceptance with 24V DC nominal rating for compatibility with diverse control voltage standards
- Heavy-Duty Output Contacts: 5A @ 250V AC or 30V DC switching capacity per relay output for direct actuator control
- Multi-Level Isolation: 1500V input-to-output and channel-to-bus isolation protects against ground potential differences and transient overvoltages
- Extended Temperature Performance: -25°C to +55°C operating range supports installation in non-climate-controlled substations and industrial facilities

Target Application Environments
1. Electrical Substation Protection & Control
Integrates seamlessly with ABB Relion 650, 615, and 670 series protection relays to expand binary I/O capacity for breaker status monitoring, isolator position feedback, alarm signal acquisition, and remote trip command execution in medium and high-voltage substations.
2. Industrial Power Distribution Systems
Serves as the interface layer between protective relays and plant-wide SCADA systems in manufacturing facilities, enabling real-time status reporting of motor control centers, transformer tap changers, capacitor bank switching, and emergency shutdown circuits.
3. Renewable Energy Generation Facilities
Facilitates grid interconnection protection schemes in solar farms and wind power plants by processing generator breaker auxiliary contacts, synchronization check signals, anti-islanding detection inputs, and remote disconnect commands from utility SCADA systems.
4. Critical Infrastructure Monitoring
Deployed in water treatment plants, data centers, and transportation systems to interface protective relays with building management systems (BMS), providing fault annunciation, equipment status visibility, and coordinated load shedding during emergency conditions.
5. Retrofit & Modernization Projects
Enables cost-effective expansion of legacy ABB protection relay installations without complete system replacement, supporting phased migration strategies and maintaining operational continuity during substation upgrades.
System Integration Benefits
Simplified Wiring Architecture: Group isolation design reduces the number of external isolation relays required, cutting panel space requirements by up to 40% and lowering installation labor costs in multi-feeder protection schemes.
Enhanced Diagnostic Capabilities: LED status indicators on each I/O channel enable rapid visual verification during commissioning and troubleshooting, reducing mean time to repair (MTTR) by eliminating the need for external test equipment during routine maintenance.
Noise Immunity in Harsh Environments: 1500V isolation voltage withstands the electromagnetic interference (EMI) and ground potential rise (GPR) conditions typical of high-voltage switchyards, ensuring signal integrity during fault events and switching transients.
Flexible Output Configuration: Form-C relay contacts support both normally-open and normally-closed wiring schemes, accommodating fail-safe design requirements and enabling direct replacement of obsolete I/O modules from other manufacturers.
Backward Compatibility: Maintains pin-compatible footprint with earlier ABB Relion I/O modules, allowing drop-in replacement during service upgrades without control cabinet modifications or relay reprogramming.
Compatible ABB Relion Protection Platforms
- REC650 - Transformer & Feeder Protection & Control IED
- REF615 - Feeder Protection & Control Relay
- REF610 - Feeder Protection Terminal
- REB670 - Busbar Protection Relay
- RET670 - Transformer Protection IED
- REG670 - Generator/Motor Protection Relay
- REL670 - Line Differential Protection System
The module communicates via the Relion backplane bus, automatically recognized by the host relay upon installation with no manual configuration required for basic I/O mapping.
Installation & Commissioning Considerations
Mount the module on standard 35mm DIN rail within the ABB Relion relay enclosure or separate marshalling cabinet. Ensure adequate ventilation clearance (minimum 50mm above and below) for convection cooling. Connect field wiring to screw-clamp terminals using 0.5-2.5mm² copper conductors with ferrules. Verify input voltage polarity and output contact ratings before energization. Consult ABB technical manual 1MRK506xxx-UEN for detailed wiring diagrams and relay configuration parameters.
