ABB DSDI 110AV1 (3BSE018295R1) is a Digital Input Board for ABB systems, with 32 channels, 24VDC input, opto-isolation. Supports event detection, operates stably, meets standards, ensuring reliable field signal acquisition.
Dimensions: 216mm × 18mm × 225mm (255mm as alternative; compact form factor for dense rack installations in control cabinets)
Weight: 0.34kg (0.1kg as alternative; lightweight design reduces rack load and eases handling)
Installation: 35mm DIN rail (tool-less mounting for rapid deployment and on-site replacement)
Environmental Ratings:
Operating temperature: -25°C to +60°C
Storage temperature: -40°C to +85°C
Relative humidity: 5–95% (non-condensing)
Protection class: IP20 (suitable for control cabinets)
Compliance: Meets EU directives 2014/30/EU (EMC) and 2014/35/EU (LVD); exempt from EU Directive 2011/65/EU (RoHS) per Article 2(4); electromagnetic immunity compliant with industrial-grade IEC 61000-6-2 standards.
Key Functional Features
High-Density Signal Acquisition: 32 channels enable monitoring of up to 32 digital field devices with a single board—reducing the number of modules needed in S100 I/O racks and saving cabinet space (critical for large-scale process plants).
Redundant Configuration Support: Integrated into redundant digital input kits (e.g., 3BNP000030R2) — supports 1+1 redundancy to ensure uninterrupted signal acquisition if a primary board fails, ideal for safety-critical applications.
Legacy System Compatibility: Exempt from RoHS requirements to maintain compatibility with ABB’s legacy Advant OCS systems (e.g., MasterPiece 200, Advant Controller 450 Version 2.3), avoiding costly upgrades for existing installations.
Reliable Signal Detection: Engineered for industrial noise immunity (implied via S100 I/O system standards) — minimizes false triggers from electromagnetic interference (EMI) caused by nearby motors, VFDs, or power cables.

Optimized Channel Configuration & Signal Adaptability
Equipped with 32 independent digital input channels, grouped into 4 sets of 8 channels for organized signal management, suitable for multi-sensor and multi-device signal acquisition scenarios.
Supports 12-48V DC wide input voltage range (standard 24V DC), compatible with most industrial digital signal sources such as proximity switches and limit sensors.
Offers dual signal processing modes: scanning-driven for continuous steady-state monitoring and interrupt-driven for high-priority event response, matching different control system real-time requirements.
Robust Anti-Interference & Isolation Design
Integrates optical isolation technology between input circuits and the main control unit, effectively blocking ground loops and electrical noise interference from industrial sites.
Meets industrial-grade electrostatic discharge (ESD) protection standards, with ±8 kV contact discharge and ±15 kV air discharge resistance, avoiding component damage during installation and maintenance.
Complies with IEC 61000-6-2 electromagnetic compatibility (EMC) standards, resisting interference from nearby frequency converters, high-voltage motors, and other equipment—ensuring accurate signal reading without false triggers
Space-Saving Installation & Durable Construction
Features a compact form factor with dimensions optimized for dense rack layouts (typical specs: ~216mm length × 18mm height × 225mm width), fitting into narrow control cabinet spaces.
Supports tool-less mounting on 35mm DIN rails, enabling quick installation and module replacement, reducing on-site construction time.
Adopts high-grade engineering plastic housing and corrosion-resistant metal contacts, withstanding harsh industrial conditions (temperature fluctuations, humidity) and extending service life.
