The ABB DSDI110A 57160001-AAA delivers reliable digital signal acquisition for demanding automation environments. This digital input board integrates seamlessly into ABB control systems, offering robust opto-isolation and flexible event detection.

Key Technical Specifications

Advanced Digital Input Architecture

This module features 32 opto-isolated digital input channels arranged in four independent groups of eight. Each group provides complete galvanic isolation, effectively eliminating ground loop interference in mixed-voltage installations.

The DSDI110A 57160001-AAA accepts 24 VDC input signals with exceptional noise immunity. Its opto-coupled design ensures reliable operation even in electrically harsh environments typical of heavy manufacturing.

Flexible Event Detection Modes

Engineers can configure event detection through either scanning mode for routine monitoring or interrupt control for time-critical responses. This dual capability allows the ABB DSDI110A to handle both periodic data acquisition and immediate fault notification.

The module’s scanning cycle processes all 32 channels within 2 ms. Meanwhile, interrupt mode triggers CPU attention within microseconds of an input state change.

Mechanical Design and Integration

Weighing approximately 0.35 kg, this compact digital input board measures 220 mm x 100 mm x 30 mm. Its rigid PCB construction withstands industrial vibration, while front-panel LED indicators display channel status at a glance.

The board connects via a 50-pin female ribbon connector, compatible with standard ABB termination units. Each of the four input groups shares a common return line, simplifying field wiring.

System Compatibility

As part of ABB’s distributed control system portfolio, the DSDI110A 57160001-AAA interfaces directly with ABB AC 800M controllers and S800 I/O racks. It supports hot-swapping in redundant configurations, minimizing production downtime during maintenance.

Environmental and Regulatory Compliance

The module operates reliably from 0°C to +60°C with 5% to 95% non-condensing humidity. It consumes just 2.5 W typically, contributing to energy-efficient cabinet designs.

Regarding environmental directives, this product holds RoHS exemption under 2011/65/EU Article 2(4)(c), (e), (f), and (j). This exemption applies to equipment specifically designed for large-scale industrial installations.
