ABB AU3074 module

Product Introduction

The ABB AU3074 is a communication assembly module designed for ABB pressure/differential pressure/level transmitters (such as the 266HSH series). It features an integrated display and supports HART communication. This plug-in module is field-replaceable, facilitating on-site maintenance and upgrades.

Detailed Specifications

Advantages & Features

1. Integrated Display
   The AU3074 includes an LCD screen, allowing direct reading of measurement values, statuses, error codes on-site—reducing reliance on external handheld HART devices.

2. Hot-Swap / Easy Maintenance
   The module can be replaced or upgraded while the system is in service (depending on site conditions), minimizing maintenance time and improving availability.

3. Standard HART Communication
   Offers standard HART protocol support, enabling communication with DCS/PLC systems, HART handheld devices, and host control systems for remote monitoring, parameterization and diagnostics.

4. High Compatibility
   Specifically designed for ABB 266HSH / 266 transmitters, ensuring hardware compatibility for replacement or upgrade purposes.

5. Cost Reduction
   Replacing only the communication module is less expensive than replacing the entire transmitter and reduces downtime losses.

Application Areas

As a communication module, the AU3074 is used in industrial systems requiring pressure, differential pressure, or level measurement combined with remote communication and diagnostics capabilities. Typical application domains include:

• Oil & gas exploration, production and pipeline systems

• Chemical and petrochemical process control

• Power generation and plant monitoring

• Water treatment and municipal water systems

• Pharmaceutical, biotech, and food processing

• Broad industrial automation systems involving pressure/level measurement and remote communication
