2. Key Features

• IRC5 Safety System Integration: Custom-engineered for ABB IRC5 controllers and SafeMove2 safety software—seamlessly exchanges safety data with the IRC5 core control board (DSQC503A) via the 1Gbps Safety Bus, ensuring no latency in safety fault response.
• SIL 2/PL d Safety Compliance: Dual-channel safety I/O (8 inputs, 4 outputs) meets global safety standards—prevents unintended robot motion if safety interlocks (e.g., emergency stops, light curtains) are triggered, protecting operators and equipment.
• Combined Safety & Standard I/O: Integrates 8 safety inputs, 4 safety outputs, 16 standard digital inputs, and 12 standard digital outputs in one board—eliminates the need for separate safety and I/O modules, reducing IRC5 slot usage and simplifying wiring.
• 2.5kVrms Isolation: Industrial-grade isolation between safety circuits, standard I/O, and the IRC5 backplane protects sensitive safety logic from ground loops and voltage transients (common in factory power grids)—ensures reliable safety signal processing.
• Configurable Standard I/O: Sinking/sourcing selectable for standard digital inputs (via RobotStudio) and PTC fuse protection for outputs—supports diverse peripherals (e.g., NPN/PNP sensors, small actuators) without additional hardware.
• Real-Time Safety Diagnostics: Logs up to 100 safety events (e.g., emergency stop triggers, safety gate openings) and provides real-time I/O status via RobotStudio—enables technicians to trace safety faults and optimize robot cell safety.
• Rugged Industrial Design: Reinforced PCB edges, EMC compliance, and wide temperature range (-20℃~+70℃ storage) withstand harsh manufacturing conditions (vibration, electrical noise, temperature fluctuations)—extends service life to ≥8 years.

3. Application Fields

• IRC5 Robot Cell Safety & I/O Expansion: Primary application—enhances safety and I/O capacity in:
  • Automotive Manufacturing: Processes safety signals (emergency stops, safety gates) for IRB 6700 welding robots; uses standard I/O to connect part presence sensors and gripper solenoids, supporting multi-robot assembly lines.
  • Heavy Material Handling: Manages safety interlocks (light curtains, load limit switches) for IRB 8700 robots in steel mills; standard outputs power conveyor drive actuators, synchronizing material flow with robot motion.
  • Electronics Production: Controls safety for IRB 120 pick-and-place robots (e.g., safety doors for cleanrooms); standard I/O connects PCB position sensors and SMT feeder triggers, ensuring precise component placement.
• Safety-Critical Automation: Ensures compliance in:
  • Aerospace Manufacturing: Monitors safety interlocks for IRB 7800 drilling robots (e.g., tool changer safety locks); safety outputs disable robot drives if faults occur, preventing damage to expensive aircraft components.
  • Pharmaceutical Production: Processes safety signals for sterile IRB 4600 robots (e.g., cleanroom access interlocks); standard I/O connects vial detection sensors and labeling actuators, meeting GMP safety requirements.
• High-Density I/O Requirements: Supports peripheral-rich robot cells in:
  • Food & Beverage Packaging: Uses standard I/O to connect case presence sensors, labelers, and reject mechanisms for IRB 360 delta robots; safety I/O monitors washdown-compatible emergency stops, complying with food industry safety standards.
  • Warehouse Logistics: Expands I/O for IRC5-controlled palletizing robots (IRB 660); standard I/O connects barcode scanners and conveyor diverters, while safety I/O monitors warehouse personnel safety gates.

4. Precautions

• IRC5 Exclusivity: Use exclusively with ABB IRC5 controllers. Never install in older ABB controllers (e.g., S4C+) or non-ABB systems—electrical and communication mismatches will damage the board or compromise safety.
• Safety Circuit Wiring:
  • Use twisted-pair shielded cables for safety I/O connections (minimum 24AWG). Ground the cable shield at the field device end (single-point grounding) to avoid ground loops that corrupt safety signals.
  • Wire safety inputs as dual-channel (redundant) per EN ISO 13849-1—single-channel wiring invalidates PL d/SIL 2 compliance and creates safety risks.
• External Safety Power Supply: Always use an isolated 24V DC power supply for safety circuits (do not share with standard I/O or IRC5 backplane power). Shared power sources cause voltage drops during high loads, leading to false safety faults.
• Safety Configuration:
  • Configure safety logic (e.g., emergency stop response, safety gate monitoring) via ABB SafeMove2 software only—unauthorized modifications violate safety standards and void compliance certifications.
  • After replacing the DSQC676, re-validate safety functions with ABB safety validation tools to ensure PL d/SIL 2 compliance.
• Overload Prevention:
  • Do not exceed 2A per safety output channel or 6A total (safety outputs). Overloading triggers PTC fuses, disabling safety actuation (e.g., drive enable) and requiring manual reset.
  • For standard outputs, limit current to 1A per channel and 8A total—overloads cause permanent output damage.
• Maintenance Checks: Inspect quarterly (with IRC5 powered off and disconnected):
  • Visually check the board for damaged components (bulging capacitors, burnt traces) or loose connectors—replace the board if damage is found (no field repairs possible).
  • Test safety inputs by triggering emergency stops/safety gates and confirming the SAFE LED turns red (fault state) and robot motion stops.
  • Verify standard I/O functionality via RobotStudio: energize outputs and measure voltage at terminals; activate inputs and confirm LED status.
• Fault Handling: If the SAFE or S-BUS LED turns red (safety fault):
  • Power off the IRC5 controller and disconnect AC power.
  • Check safety I/O wiring for short circuits or loose connections (e.g., a damaged emergency stop cable).
  • Use RobotStudio to retrieve safety fault logs—address the root cause (e.g., safety gate wiring fault) before restarting the controller
