Module Overview

The DI828 (Article Number: 3BSE069054R1) is a high-density 16-channel digital input module engineered by ABB for the S800 I/O platform. It processes 120 V AC or DC input signals with individually isolated channels for superior noise immunity. Featuring dedicated voltage supervision channels and G3 corrosion protection, it delivers robust reliability in harsh industrial automation environments.

Configuration and Technical Specifications Matrix

Specification Category	Technical Parameter Details

Filter & Update Times	Selectable digital filter times (2.5, 5, 10, 20 ms); 5/10 ms analog filter
Matching MTU Units	TU851 (Keying Code: TU851)
Physical Dimensions & Weight	45 mm width x 119 mm height x 102 mm depth; 0.15 kg

Installation and Mounting Guidelines

Mount the unit onto a compatible TU851 Modular Terminal Unit ensuring correct keying alignment.
Configure channel 1 as a dedicated voltage supervision input for channels 2 through 8 if group monitoring is required.
Configure channel 16 as a dedicated voltage supervision input for channels 9 through 15.
Limit maximum field cable lengths to 200 meters for AC signals and 600 meters for DC signals.
Ensure vertical mounting setups do not exceed a maximum ambient temperature limit of 40 C in compact MTU housings.

Advanced Diagnostics and Fault Detection

The module performs comprehensive real-time status monitoring via front panel LEDs indicating Fault, Run, Warning, and individual channel states ("0" or "1"). If voltage feeding the supervision channels (1 or 16) drops or disappears, a channel error triggers automatically and activates the warning status flag, which transmits directly across the Modulebus for rapid system diagnostics.

Target Applications and Environment

Power Generation Plant Turbine Auxiliary Control Panels
Heavy Industrial Process Distribution and Switchgear Interlocks
Marine and Offshore Automation Systems (ABS, BV, DNV, LR certified)
Harsh Chemical Environments requiring ISA-S71.04 G3 Corrosion Resistance
Oil and Gas Emergency Shutdown (ESD) System Periphery

Global PLC Spare HUB Insight

Instrumentation specialists deploying the DI828 module note that utilizing the integrated voltage supervision feature on channels 1 and 16 effectively eliminates the need for external monitoring relays in 120V control architectures. For example, wiring group power feeds through these supervision pins allows the control system to instantly detect blown group fuses before secondary control loops fail.

Logistics, Fulfillment, and Warranty

Expedited order processing and dispatch within 24 to 48 hours of confirmation.
Reliable global shipping channels coordinated via FedEx, UPS, and DHL.
Packaged securely in antistatic industrial materials to prevent physical transit damage.
Fully backed by a comprehensive 12-month manufacturer replacement warranty.

Buying Guide and Engineering FAQ

Q: Can this digital input unit process both AC and DC field signals simultaneously?

A: Yes, the hardware supports mixed 120 V AC or DC inputs across its 16 channels, provided appropriate input filtering and voltage ranges are respected.

Q: What happens if the power source feeding channel 1 supervision fails?

A: A channel error flag is raised for channels 2 through 8, the warning LED illuminates, and the error code reports directly via the Modulebus.

Q: What is the primary function of the selectable digital filter times?

A: They allow engineers to suppress high-frequency electrical noise and contact bounce ranging from 2.5 ms to 20 ms depending on application speed.

Q: Why is max ambient temperature restricted when using compact vertical MTUs?

A: Compact vertical stacking limits natural convection cooling, necessitating a reduced ambient limit of 40 C to protect internal components.

Q: How do I select the correct terminal unit for replacement tasks?

A: Always verify that your base rack utilizes the TU851 terminal unit matching the specific TU851 keying code requirements.
