Description

Product Overview

In industrial automation control systems, the ABB DSAI130D 3BSE003127R1 acts as the “sensory nerve ending”—it is responsible for converting continuous variables from the physical world (such as pressure, temperature, and flow) into digital signals recognizable by the PLC.

This module is a standard I/O expansion module for ABB AC500 and Freelance control systems. It features a compact DIN rail mounting design and can be directly inserted into S500 or compatible I/O bases (such as SC510/SC520). Its core advantages lie in high precision, strong isolation, and engineering friendliness: each input channel is independently isolated, effectively preventing common-mode interference; the 16-bit ADC ensures that even small signal changes are accurately captured; and it supports wire break detection, significantly improving system safety.

📌 Note: Although the model suffix is ”D”, the DSAI130D is not a dedicated HART protocol module. It can transmit HART signals superimposed on 4–20mA (pass-through), but it does not have HART master decoding capabilities. To actively read HART data, a HART-compatible CPU or dedicated communication module is required.

Main Features and Advantages

* High-precision signal acquisition: 16-bit resolution + ±0.1% accuracy, meeting demanding process control requirements. * **Full Channel Electrical Isolation:** Effectively suppresses field noise and ground loop interference, ensuring system stability.

* **Intelligent Diagnostic Function:** Real-time monitoring of signal breaks, short circuits, or out-of-range values, providing early warning of potential faults.

* **Flexible Configuration:** Range, filtering parameters, and alarm thresholds can be set remotely via programming software (such as Automation Builder or Control Builder M).

* **Plug-and-Play:** Supports hot-swapping (in compatible systems), eliminating the need for downtime during maintenance.

* **HART Signal Passthrough:** Allows HART signals to be transmitted through the module to a dedicated HART multiplexer or handheld terminal.

Typical Application Scenarios

Water Treatment Plants: Collecting 4–20mA signals from level meters, turbidity meters, and pH electrodes.

Boiler Control Systems: Monitoring key parameters such as pressure, temperature, and steam flow.

Chemical Reactors: Real-time tracking of reaction temperature and feed flow rate for precise proportioning.

Energy Management: Connecting to smart meters or power transmitters for energy consumption data acquisition.

OEM Equipment Integration: Serving as a standardized I/O interface for quick integration of third-party sensors.

**Installation and Configuration Recommendations**

Base Plate Compatibility: Must be installed on an ABB S500 series compatible carrier (e.g., SC510 3BSE003832R1).

Wiring Standards: Use shielded twisted-pair cables, with the shield grounded at a single point to avoid interference.

Wire Break Detection: Activate the Wire Break function in the software to automatically detect sensor wire breaks.

Signal Filtering Settings: For signals with significant fluctuations (e.g., flow rate), it is recommended to enable software filtering to smooth the data.

Redundancy Considerations: For critical loops, consider using dual modules with voting logic to improve availability.

**Lifecycle and Procurement Recommendations**

As of 2026. the DSAI130D 3BSE003127R1 is still in “Active” status and widely used in existing AC500/Freelance systems worldwide.

New Projects: Although ABB is now primarily promoting AC500-eCo and AC800M, the DSAI130D is still used in small and medium-sized projects due to its cost advantages.

Spare Parts Procurement: It is recommended to stock 1–2 units for emergency replacement, especially during the modernization of older production lines. Authenticity Verification: Refurbished modules exist on the market; please look for the genuine ABB factory label, serial number, and anti-counterfeiting seal.

Shenzhen Changxin promises: All ABB DSAI130D 3BSE003127R1 modules supplied are genuine, brand-new ABB original products with traceable origins and support official verification. Each module undergoes power-on function testing, channel accuracy calibration, and appearance quality inspection, and comes with a 12-month warranty and professional technical support for worry-free operation and maintenance.

Technical Summary (English):

The ABB DSAI130D 3BSE003127R1 is an 8-channel analog input module for the AC500 and Freelance automation platforms, designed to accurately acquire 0/4–20 mA current signals from field transmitters. Featuring 16-bit resolution, channel-to-channel isolation (500 V AC), and wire-break detection, it ensures reliable data acquisition in electrically noisy industrial environments. While it supports HART signal pass-through, it does not decode HART protocol natively. Ideal for process control applications in water treatment, power, and manufacturing, this module offers high precision, easy integration, and robust diagnostics.
