Description
Product Introduction
The ASEA DSAI 145 Analog Input Unit, part number 2668 184-264, is an industrial automation I/O module associated with the ABB Advant Master control system family. Originally developed under the ASEA name, this module is used to interface analog field signals with compatible control and monitoring systems.
The DSAI 145 receives analog signals from connected instrumentation and makes measurement data available to the control system for process monitoring, data acquisition, and control applications. It is intended for installation in compatible system hardware and must be matched to the appropriate rack, interface, and configuration.
This module is suitable for maintenance and replacement applications where the original equipment uses the same DSAI 145 model and hardware configuration. Verify the product identification, terminal arrangement, and system documentation before ordering or installation.
