ABB REJ603 BNNNNNNBZA Add-on HMI Kit | Feeder Protection Interface

ABB REJ603 BNNNNNNBZA Add-on HMI Kit - Enhanced Operator Interface Solution

The ABB REJ603 BNNNNNNBZA delivers advanced human-machine interface capabilities for REJ603 feeder protection relays deployed in electrical distribution systems. This plug-and-play HMI kit provides local display, keypad navigation, and real-time monitoring functionality, enabling substation operators to access protection settings, event logs, and diagnostic information directly at the relay without requiring SCADA connectivity or external engineering tools.

Technical Specifications

Functional Capabilities

Local Display & Navigation: The graphical LCD provides clear visualization of protection status, measured values, and alarm conditions without requiring connection to SCADA or engineering workstations. Multi-level menu structure enables intuitive navigation through settings, measurements, and event records using dedicated function keys.

Real-Time Monitoring: Displays live electrical parameters including voltage, current, frequency, power factor, and active/reactive power for all monitored phases. Trend data and min/max values help operators identify abnormal operating conditions before they escalate to protection trips.

Event & Fault Recording: Provides immediate access to the last 100 protection events with timestamp, fault type, and measured values at the moment of trip. This local diagnostic capability accelerates troubleshooting during outage restoration without waiting for SCADA data retrieval.

Settings Access: Authorized personnel can view and modify protection settings directly through the HMI using password-protected access levels. This eliminates the need for laptop computers and specialized software during commissioning or maintenance activities in remote substations.

Industrial Applications

Utility Distribution Substations: Enhances operator situational awareness in unmanned or remotely monitored substations where SCADA communication may be unavailable during network outages. The local HMI ensures critical protection information remains accessible for emergency response and system restoration.

Industrial Power Distribution: Supports maintenance teams in manufacturing facilities, data centers, and commercial buildings where feeder protection relays control critical electrical distribution circuits. Local access to event logs and settings reduces downtime during troubleshooting and commissioning.

Renewable Energy Installations: Provides on-site monitoring for solar farm and wind turbine feeder protection systems located in remote areas with limited communication infrastructure. Operators can verify protection status and retrieve fault data during site visits without specialized equipment.

Mining & Heavy Industry: Enables field technicians to diagnose protection issues in harsh environments where bringing laptop computers into hazardous or dusty areas is impractical. The rugged HMI withstands temperature extremes and vibration common in mining operations.

Marine & Offshore Platforms: Facilitates shipboard electrical system monitoring and offshore platform power distribution management where space constraints and environmental conditions demand compact, reliable operator interfaces.

Installation & Integration

The REJ603 HMI kit installs in minutes through a plug-and-play connection to the relay's internal communication port. No external wiring, power supply, or configuration required—the HMI automatically detects the connected REJ603 variant and configures display parameters accordingly.

Mounting Procedure: Remove the REJ603 front cover, connect the HMI ribbon cable to the designated internal connector, secure the HMI module to the front panel mounting points using provided hardware, and replace the front cover. The relay automatically recognizes the HMI upon power-up.

User Access Control: Three-level password protection (Viewer, Operator, Administrator) restricts access to sensitive settings and control functions. Password management performed through the HMI keypad or via PCM600 engineering software for centralized security administration.

Operational Features

• Multi-Language Support: Configurable display language selection supports global deployments with localized operator interfaces
• Backlight Control: Automatic backlight dimming conserves power and extends display lifespan, with manual override for high-ambient-light environments
• Alarm Indication: Visual and audible alarm notification for protection trips, communication failures, and self-diagnostic faults
• Measurement Logging: Stores min/max values for voltage, current, and power parameters with timestamp for trend analysis
• Trip Circuit Monitoring: Displays trip coil continuity status and circuit breaker position feedback for comprehensive switchgear monitoring
• Self-Diagnostics: Continuous monitoring of HMI hardware, display integrity, and communication link to REJ603 relay

Maintenance & Reliability

The HMI kit features solid-state construction with no moving parts, ensuring long-term reliability in substation environments. The membrane keypad withstands over 1 million key presses, while the LCD backlight provides 50,000+ hours of operation before requiring replacement.

Preventive Maintenance: Annual inspection includes cleaning the front panel with non-abrasive cloth, verifying keypad responsiveness, and checking display clarity. No periodic calibration or software updates required for basic HMI functionality.

Field Replacement: Hot-swappable design allows HMI replacement without de-energizing the REJ603 relay or interrupting protection functions. Configuration data stored in the relay ensures automatic restoration of display settings upon HMI reconnection.

Compliance & Standards

The REJ603 HMI kit meets international standards for protection relay accessories:

• IEC 61850: Compliant with substation automation communication protocols
• IEC 60255: Measuring relays and protection equipment standards
• CE Marking: Complies with Low Voltage Directive and EMC Directive for European installations
• UL Listed: Certified for North American electrical distribution applications
• IEEE C37.90: Withstand capability for electrical fast transient and surge immunity
