The ABB DSDO131 functions as a versatile relay output board for industrial switching applications. This module handles both AC and DC loads up to 240 volts for maximum flexibility. It provides isolated relay contacts for controlling motors, solenoids, and industrial actuators. You can integrate this board into ABB automation systems for reliable discrete control.

Key Technical Specifications

We designed the ABB DSDO131 with robust relay outputs capable of switching diverse industrial loads. Its wide voltage range accommodates both AC and DC field devices without additional interfacing. The following table details the available technical parameters for this digital output board.

Detailed Functional Overview

The DSDO131 uses electromechanical relays to provide galvanic isolation between the control system and field wiring. Each output can switch AC loads up to 720VA or DC loads up to 48 watts. Consequently, this module suits applications requiring isolation for motors, contactors, and pilot devices. Its relay outputs handle inrush currents better than solid-state alternatives.

Load Handling Capabilities

This board supports AC loads up to 720VA for controlling small motors and transformers directly. For DC applications, it handles loads up to 48 watts for solenoids and DC relays. Therefore, the ABB DSDO131 offers genuine flexibility for mixed-voltage control panels. You should verify specific load characteristics against the module’s ratings before installation.

System Integration

The DSDO131 integrates with ABB’s I/O systems for coordinated industrial process control. It receives commands from the main controller through a standard backplane interface. For additional system protection components, you might also evaluate the RMS TSG TZ C Static Trip unit for your application needs. This output board represents a reliable choice for applications requiring relay isolation.
