ABB 3BSE020828R1 DSAI130DK01 Analog Input Module

The ABB 3BSE020828R1 (type designation DSAI130DK01) is an 8-channel analog input module designed for ABB's Advant Controller 400 series and the AC 800M control system. It is a key component in the S100 I/O system, used to interface with 4-20 mA analog field devices such as pressure transmitters, temperature sensors, flow meters, and level transducers. The module converts analog current signals into digital values for processing by the controller, enabling precise monitoring and control in industrial processes.

8-Channel 4-20 mA Inputs

The DSAI130DK01 provides eight analog input channels, each configurable for 4-20 mA signals. The module can accept both active (externally powered) and passive (loop-powered) 2-wire transmitters. For passive transmitters, the module supplies a regulated 24 V DC loop power (max. 30 mA per channel) directly through the input terminals, simplifying wiring and eliminating the need for external power supplies. Each channel is individually isolated from the others and from the system backplane, preventing ground loops and protecting the controller from field-side faults.

High-Speed Data Acquisition

The module samples each channel sequentially with a conversion time of 1 ms per channel, resulting in a total update cycle of 8 ms for all 8 channels. This fast update rate allows the module to capture rapidly changing process variables in applications such as flow control or pressure monitoring. The 12-bit resolution provides 4096 discrete steps over the 4-20 mA range, which is sufficient for most industrial process control requirements. An onboard filter reduces high-frequency noise to ensure stable readings.

Integration with ABB Control Systems

The DSAI130DK01 is designed for the ABB S100 I/O chassis, which connects to Advant Controller 400 or AC 800M via a dedicated I/O bus. The module is automatically recognized by the controller and can be configured using ABB's Control Builder or 800xA engineering tools. The module supports hot‑swap replacement, allowing a faulty module to be replaced without powering down the system, minimizing downtime in critical applications.

Application Domains

This analog input module is widely used in process industries including oil and gas, chemical, pharmaceutical, power generation, and water/wastewater treatment. It is typically installed in control rooms or local I/O panels to collect analog signals from field instruments. Typical applications include monitoring of pressure, temperature, flow, level, and pH, as well as integration into safety instrumented systems (SIS) where reliable analog measurement is required.
