The ABB DSAI145 analog input unit is a legacy PC board for industrial automation. This discontinued module originally acquired signals from process sensors in ABB control systems. Engineers must now identify suitable modern replacements for ongoing maintenance and upgrades.
Original Function and Technical Application
This PC board served as a critical interface for converting analog field signals. It reliably measured variables like pressure, temperature, and flow for system monitoring. Furthermore, the DSAI145 integrated with ABB’s broader hardware architecture for seamless data processing.
The module’s discontinuation necessitates careful review of legacy system documentation. Therefore, finding a functional DSAI145 unit now involves specialized industrial surplus suppliers. For example, platforms like Alibaba may list similar legacy automation spares such as the RMS-TSG-TZ-C Static Trip Unit.
Preserved Legacy Technical Specifications
Based on typical ABB industrial I/O modules from its era, the DSAI145 likely featured these specifications. Please verify all parameters against your original equipment manufacturer manuals for accuracy.
