Description

The ABB DI880 (3BSE028586R1) is a 16-channel, 24 V d.c. digital input module designed for the S800 I/O system. It supports both single and redundant configurations, making it suitable for high-availability industrial control applications. Each input channel is equipped with current limiting, EMC protection, status indication LEDs, and optical isolation to ensure robust signal processing. The module also features advanced Sequence of Events (SOE) recording capabilities with 1 ms resolution, allowing for precise diagnostics and event tracking in critical systems.

Features

  • 16 channels for 24 V d.c. inputs with current sinking.
  • Supports single or redundant system configurations.
  • 1 group of 16 channels isolated from ground.
  • Integrated Sequence of Events (SOE) function with 1 ms resolution.
  • Current-limited transducer power supply provided per input channel.
  • Advanced on-board diagnostics and input status LEDs.
  • Supports hot-swapping for maintenance without system downtime.

Applications

  • Safety Instrumented Systems (SIS): Primary input for ESD and F&G applications.
  • Oil & Gas: Monitoring of critical valves, pressure switches, and level sensors.
  • Power Generation: Turbine control and distribution protection.
  • Chemical & Petrochemical: Management of high-risk reactor inputs.
  • Marine & Offshore: Certified for harsh maritime environments.

Installation Guidelines

  • The DI880 must be installed with a compatible Module Termination Unit (MTU) such as the TU810, TU842, or TU843.
  • Mounting: Designed for horizontal or vertical DIN-rail installation. Ensure the locking mechanism is fully engaged for mechanical stability and proper electrical grounding.
  • Mechanical Keying: The module utilizes a keying code of FF to prevent incorrect module insertion into the MTU.
  • Handling: Use standard ESD precautions when handling the module.
  • Hot Swapping: The module supports hot-swapping; however, always refer to the specific S800 I/O system manual for safety procedures before removal or insertion under power.

Compliance and Certifications

The DI880 complies with EN50178, EN61131-2, and UL508 industrial standards. It is certified for use in SIL3 high-integrity applications.

FAQs

Does the DI880 3BSE028586R1 support event logging?

Yes, the DI880 features Sequence of Events (SOE) functionality, collecting logical events with a resolution of 1 millisecond and a queue capacity of up to 512 x 16 events.

What is the voltage hold-up time?
