Product Short Description
Product Description
The ABB DSDI110AV1 (3BSE018295R1) is a high-integrity digital input module designed for the S100 I/O system, integrated within the ABB System 800xA automation platform. It serves as a critical interface, converting physical on/off signals from field devices into logical data for AC 800M controllers and Advant OCS systems. A core engineering feature is its wetted contact design: the module provides internal 24 V DC power to drive passive field contacts (e.g., relays, limit switches, pushbuttons), eliminating the need for external field wiring and simplifying panel design while boosting system reliability.
Description
Engineered for robustness in harsh industrial environments, the DSDI110AV1 features group-wise galvanic isolation, integrated signal filtering, and comprehensive diagnostic capabilities. Its modular, DIN-rail mountable form factor optimizes cabinet space and supports hot-swapping for maintenance without system shutdown. As a foundational component in process and discrete automation, it ensures accurate, reliable signal acquisition for safety interlocks, sequence control, and continuous monitoring applications.

Functional Features
-
Wetted Contact & Dual Input Compatibility
- Integrates 16 isolated input channels with on-board 24 V DC power to directly drive passive contact devices (e.g., mechanical switches, relay contacts) without external field wiring, reducing installation complexity and failure points.
- Supports active 24 V DC source signals for connection to proximity sensors, photoeyes, and solid-state switches, offering flexible integration with mixed field device types.
- Configurable scan or interrupt operation allows optimization for high-speed events (interrupt) or sequential monitoring (scan), adapting to diverse process needs.
-
Superior Electrical Isolation & Noise Immunity
- Implements group-wise galvanic isolation (8 channels per group) between all inputs and the backplane, preventing ground loops and cross-talk in electrically noisy industrial environments.
- Built-in digital filtering eliminates contact bounce and electromagnetic interference (EMI), ensuring stable and accurate signal detection even in severe noise conditions.
- Robust over-voltage and reverse-polarity protection safeguard the module and connected field equipment from electrical transients and wiring errors.
-
Intelligent Diagnostics & Status Monitoring
- Features per-channel LED indicators for real-time visual feedback of signal state (ON/OFF) and channel health.
- Supports channel-specific open-circuit diagnostics, enabling precise identification of wiring faults or device failures directly from the control room, minimizing Mean Time To Repair (MTTR).
- Diagnostic data is transmitted over the S100 I/O bus to the System 800xA platform, facilitating remote monitoring, predictive maintenance, and rapid troubleshooting to reduce unplanned downtime.
-
High Reliability & Seamless System Integration
- Designed with industrial-grade components and rigorous testing to meet long-life, continuous-operation requirements, ensuring high Mean Time Between Failures (MTBF).
- Fully compatible with the S100 I/O system and AC 800M controllers, supporting hot-swappable operation for module replacement without system power-down, lowering maintenance costs and production loss.
- Automatically recognized and configured by ABB Control Builder M software, enabling rapid project deployment and simplified system integration.
- Part of ABB’s scalable S100 I/O ecosystem, supporting modular expansion to match growing system requirements.
