ABB DO880 3BSE028602R1 Digital Output Module

• Article Number: 3BSE028602R1
• Type: Digital Output
• Signal Specification: 24 V d.c. (ranging from 19.2 V to 32 V d.c.), with a maximum continuous output current of 0.5 A per channel.
• Number of Channels: 16
• Signal Type: Current sourcing with current limiting
• HART: Not supported
• SOE (Sequence of Events): Not applicable
• Redundancy: Available (supports redundant or single configuration)
• High Integrity: Yes
• Intrinsic Safety: Not applicable
• Mechanics: S800

Features and Benefits:

1. Isolated Group: The DO880 provides 16 channels for 24 V d.c. current sourcing outputs within one isolated group.
2. Loop Monitoring: It offers supervision of short and open loads with configurable limits.
3. Diagnostic Capabilities: Output switches can be diagnosed without pulsing on the outputs.
4. Advanced On-Board Diagnostics: Enhances system monitoring and troubleshooting.
5. Output Status Indicators: LEDs indicate activation or errors.
6. Degraded Mode: Supports normally energized channels even in degraded conditions (supported from DO880 PR:G).
7. Current Limitation and Protection: Protects against short circuits and over-temperature conditions.
8. Fault Tolerance: Achieves a fault tolerance of 1 (as defined in IEC 61508) for output drivers. In ND (Normally De-energized) systems, outputs can still be controlled despite errors in output drivers.
9. Certifications:
   • SIL3 (Safety Integrity Level 3) according to IEC 61508
   • Category 4 according to EN 954-1
