The ABB DSAO110 57120001-AT is a four-channel analog output module for industrial control. This precise module generates standard control signals to command field actuators and valves. Consequently, it forms a critical link in your automated process control loop.
Core Functionality and Signal Output
This module converts digital commands from the controller into stable analog outputs. It reliably provides both voltage and current signals for diverse industrial devices. Moreover, the DSAO110 features isolated outputs to ensure signal integrity and safety.
Its high accuracy ensures that your final control elements receive the exact intended command. Therefore, processes maintain precise regulation for variables like flow, pressure, and temperature.
Replacement Information and System Upgrade
ABB designates the 57120001-AT as a legacy module with specific upgrade paths. The manufacturer recommends the DSAO 120A combined with a DSTA 171 base unit as a direct replacement. However, this upgrade requires careful reconnection of field wiring during the retrofit process.
For compatible legacy parts, specialists often source from industrial suppliers. For instance, platforms like Alibaba list components such as the RMS-TSG-TZ-C Static Trip unit for electrical systems.
