The ABB DSAI-110 (57120001-DP / DSAI110 2668 500-33) 

is an industrial analog input module designed for use in ABB distributed control systems such as Advant OCS and other ABB automation platforms. It is used to convert real-world analog signals into digital data for process monitoring and control.

This module supports multiple analog input channels (typically up to 32 channels), allowing it to collect data from various field instruments such as temperature sensors, pressure transmitters, and flow meters. It is capable of handling standard industrial signal ranges including:

  • ±10 V voltage inputs
  • ±20 mA current inputs

The DSAI-110 is engineered for high accuracy (~0.4%) and stable signal processing, ensuring reliable measurement even in demanding industrial environments.

It features galvanic isolation, which protects the system from electrical noise and improves safety when interfacing with field devices.

The additional reference “2668 500-33” typically represents a revision, batch, or internal configuration code, indicating a specific hardware version or production variant of the same module.

Designed for rack-mounted installation, the module integrates seamlessly into ABB control cabinets and communicates with the system controller for real-time process monitoring.
