ABB DSAI 155 Analog Input Board

Description

The ABB DSAI 155 Analog Input Board is an industrial analog input module designed for use in distributed control systems (DCS) and industrial automation setups. It features 16 digital input channels, split into two independently isolated groups, with each group containing 8 channels and one voltage monitoring input. The module operates with an input voltage range of 18 to 30 volts DC, drawing 6 mA of current at 24V DC. Each input channel is constructed with current-limiting components, EMC protection components, an input status indicator, and an optical isolation barrier, ensuring reliable signal processing and protection against electrical interference. The integrated voltage monitoring input generates a channel error signal when input voltage is lost, and this error signal can be read via the module bus for diagnostic purposes. Boasting high reliability, flexible configuration, and fast response capabilities, the ABB DSAI 155 is suitable for a range of industrial applications including process control, manufacturing automation, and energy management, supporting seamless integration with existing industrial control systems.
