The ABB DSDI110AV1 3BSE018295R1 provides reliable 24 VDC digital signal acquisition for industrial process control. This digital input board integrates directly into ABB Advant Master systems, delivering 32 opto-isolated channels in a compact form factor.

Key Technical Specifications

High-Density Digital Input Architecture

This module features 32 digital input channels operating at 24 VDC with full opto-isolation. Each channel provides complete galvanic separation, effectively preventing ground loops and electrical interference in complex industrial installations.

The DSDI110AV1 3BSE018295R1 processes incoming signals with exceptional noise immunity. Its opto-coupled front end reliably captures status changes from field devices such as limit switches, pushbuttons, and proximity sensors.

Mechanical Design and Integration

Weighing approximately 0.38 kg, this digital input board measures 235 mm x 105 mm x 32 mm. Its robust PCB construction withstands continuous industrial vibration, while front-accessible LED indicators display real-time channel status.

The board connects through a 50-pin female D-Sub connector, ensuring secure termination with standard ABB cabling systems. Field wiring connects via compatible termination units, simplifying installation and maintenance.

System Compatibility and Configuration

ABB specifically designed this module for the Advant Master Process Control System family. The DSDI110AV1 communicates seamlessly with ABB PM802, PM803, and PM825 controllers through the S100 I/O bus.

Engineers can configure channel filtering and debounce timing through the control builder software. This flexibility allows optimization for both high-speed counting and mechanical contact de-bouncing applications.

Environmental and Regulatory Compliance

The module operates reliably from 0°C to +55°C with 5% to 95% non-condensing relative humidity. It draws only 3.0 W under typical load conditions, contributing to energy-efficient control cabinet designs.

This product holds RoHS exemption under 2011/65/EU Article 2(4)(c), (e), (f), and (j). European directives exempt large-scale industrial control equipment from certain substance restrictions due to specific installation requirements.

Application Versatility

Industrial facilities deploy the ABB DSDI110AV1 3BSE018295R1 across numerous applications. These include conveyor system monitoring, batch process sequencing, safety interlock checking, and equipment status indication.

Each of the 32 input channels accepts 24 VDC signals from standard industrial sensors. The module maintains consistent performance across the full operating temperature range without derating.
