New ABB 3BSE069054R1 DI828 High Voltage Digital Input

Product Overview

The ABB DI828 (3BSE069054R1) functions as a high-voltage digital input interface within the S800 I/O family, specifically designed for use with AC 800M controllers. This 100% brand new and original module excels in acquiring 120 V a.c./d.c. signals from field devices such as limit switches, pushbuttons, and auxiliary contacts. Unlike standard density modules, the DI828 provides individual isolation for each of its 16 channels, ensuring superior protection against cross-channel interference and electrical faults in demanding utility and process environments.

Technical Specifications

Engineering Advantages

• Individual Channel Isolation: The DI828 provides galvanic isolation for every single channel. This architecture prevents a fault or ground loop on one field circuit from migrating to other channels or damaging the backplane bus, which significantly increases overall system availability.

• High-Voltage Versatility: This module handles both 120 V a.c. and 120 V d.c. signals natively. This flexibility allows engineers to standardize on a single I/O type for diverse field signal requirements across power generation and water treatment facilities.

• Robust Dielectric Strength: With a 2000 V a.c. dielectric test voltage rating, the DI828 survives the transient surges and noise common in high-interference industrial environments. It provides a stable bridge between high-voltage field wiring and low-voltage controller logic.

• Maintenance Efficiency: The hot-swappable design permits module replacement without interrupting the power or communication to the rest of the S800 I/O station. Integrated status LEDs provide immediate visual confirmation of input states, drastically reducing the Mean Time to Repair (MTTR).

• Compact Footprint: Despite its high insulation ratings, the module maintains a slim 4.5 cm width. This maximizes rail density in control cabinets, allowing for more I/O points in a smaller enclosure.

FAQs

• Can the DI828 be used with 24 VDC signals?

  No. The DI828 is specifically engineered for 120 V a.c./d.c. nominal signals. For 24 VDC applications, you should utilize the standard DI810 or DI818 modules to ensure proper signal threshold detection.

• What is the benefit of the Rev. PR:A version?

  The "PR:A" designation refers to the hardware revision. Using current-generation revisions ensures compatibility with the latest ABB Control Builder M and System 800xA engineering tools while benefiting from the most recent component optimizations.

• Does this module require a specific termination unit?

  Yes, you must install the DI828 into a compatible S800 Module Termination Unit (MTU), such as the TU810 or TU812. The choice of MTU depends on your preference for screw terminals or spring-loaded connections.

• Is the module suitable for safety-related applications?

  While the DI828 is a highly reliable industrial module, always verify the Safety Integrity Level (SIL) requirements of your process. For dedicated safety loops, ABB offers specific "S" versions within the S800 family (e.g., DI880) that carry SIL3 certification.
