ABB DI885 3BSE013088R1 Sequence of Events Digital Input Module | S800 I/O

Product Overview

The ABB DI885 (3BSE013088R1) functions as a high-precision Sequence of Events (SOE) Digital Input module within the S800 I/O family. This module captures 8 channels of 24/48V DC discrete signals, specifically designed for applications requiring millisecond-accurate event logging. We supply this unit as 100% Brand New and Original, providing the essential hardware for system repairs, capacity upgrades, or functionality updates in existing DCS architectures. It serves as a critical diagnostic tool for identifying the root cause of plant trips by recording signal transitions with extreme temporal resolution.

Technical Specifications

The DI885 manages 8 independent channels organized in a single group to ensure high-speed data capture:

Engineering Advantages

• Millisecond Event Resolution: The DI885 hardware time-stamps incoming signal transitions directly at the module level. This eliminates network scanning delays, allowing the DCS to reconstruct the exact chronological order of field events during rapid process upsets or system trips.

• Dual-Voltage Versatility: The module accepts both 24V DC and 48V DC inputs. This flexibility allows engineers to standardize on a single I/O type across different field instrument voltage standards, simplifying spare parts logistics for diverse plant sections.

• Compact High-Density Design: The 45 mm slim profile maximizes the utilization of DIN-rail space. This design permits the integration of precision SOE monitoring into existing S800 I/O clusters without requiring substantial cabinet expansion or mechanical redesign.

• Robust Signal Isolation: A 50V rated isolation barrier protects the internal ModuleBus logic from field-side electrical disturbances. This barrier prevents ground loops and transient spikes from compromising the integrity of the overall control system.

• Seamless Compatibility for Upgrades: As a specialized spare part, the DI885 ensures perfect backward compatibility for systems placed on the market before July 2017. It docks directly into standard TU810 or TU812 termination units, facilitating rapid "plug-and-play" maintenance and capacity expansion.

FAQs

• Does the DI885 support standard digital input functions?

  Yes. While specifically designed for SOE tracking with 1ms resolution, the DI885 also functions as a standard digital input module for routine status monitoring within the AC 800M environment.

• Is this module compliant with current RoHS 2 directives?

  No. The DI885 is not RoHS 2 2011/65/EU compliant. ABB designates this part exclusively as a spare for the repair, reuse, or upgrading of systems originally deployed before July 22, 2017.

• Is this a refurbished or used unit?

  Absolutely not. We guarantee this DI885 (3BSE013088R1) is 100% Brand New original hardware. It arrives in the original ABB factory packaging with all serial numbers, security seals, and technical documentation intact.

• Which termination unit should I use for 48V applications?

  The DI885 is compatible with the TU810, TU812, TU814, and TU830. Always v
