Product Description
Product Overview

The ABB AO2020 URAS26 0242919683/1030 is an infrared gas analyzer module designed for the ABB Advance Optima AO2020 integrated analyzer system. It employs non-dispersive infrared (NDIR) measurement technology to continuously monitor gas or vapor components in industrial process and emission monitoring applications.

The URAS26 module is typically used to measure infrared-absorbing gases such as CO, CO₂, NO, SO₂, NH₃, H₂O, and hydrocarbons, depending on configuration. It can be installed in an AO2020 19-inch rack-style analyzer housing and integrated with DCS, PLC, or data acquisition systems via analog outputs and digital communication interfaces.

Because the suffix 0242919683/1030 may define specific gas components, measuring ranges, power supply, output options, and communication protocols, the exact configuration must be verified with the product nameplate or official ABB documentation before purchase.

Frequently Asked Questions
Is the AO2020 URAS26 a general I/O module?

No. It is an NDIR infrared gas analyzer module for the ABB Advance Optima AO2020 system, not a general-purpose analog output card.

What gases can the URAS26 measure?

The URAS26 is typically used for infrared-absorbing gases such as CO, CO₂, NO, SO₂, NH₃, H₂O, and hydrocarbons. The exact gas and range depend on the module configuration.

Does it support 4–20 mA output?

Yes. AO2020 analyzer modules typically support 0/2/4–20 mA analog outputs, but the available outputs should be confirmed with the nameplate or datasheet.

Do you provide datasheets?

We can provide available product information upon request. For official specifications, always refer to the ABB datasheet or authorized documentation.
