Features 4-20 mA analog output, digital communication options (Ethernet, Modbus, PROFIBUS), and self-diagnostics. Compatible with Advance Optima AO2040 platform and other modules. Ideal for hydrogen purity, process gas analysis, and spare-part replacement. 1-year warranty.
Product Description
Product Overview

The ABB AO2040-CALDOS27 is a gas analyzer configuration based on the ABB Advance Optima AO2040 platform, equipped with a Caldos27 thermal conductivity analyzer module. It is designed for continuous measurement of binary gas mixtures with different thermal conductivities, such as hydrogen, helium, argon or methane in a background gas.

Caldos27 is a widely used thermal conductivity measurement technology in ABB gas analyzers. It can be combined with other analyzer modules such as Uras26 or Magnos206 depending on system configuration. The AO2040 platform provides analog outputs such as 4-20 mA, and may support Ethernet, Modbus, PROFIBUS or other digital communication interfaces for integration with DCS, PLC or SCADA systems.

Because "AO2040-CALDOS27" describes a platform plus measurement module rather than a single fixed order code, the exact gas components, measuring range, number of channels, communication options and supply voltage must be verified with the product nameplate or official ABB documentation before purchase.

FAQ
Is AO2040-CALDOS27 a general I/O module?

No. It refers to an ABB AO2040 gas analyzer equipped with a Caldos27 thermal conductivity measurement module, not a general-purpose PLC analog output card.

What gases can Caldos27 measure?

Caldos27 is typically used for binary gas mixtures with different thermal conductivities, such as H₂ in air or N₂, He in air, Ar in O₂, and CH₄ in H₂. The exact application must be confirmed with the nameplate or datasheet.

Does AO2040 support 4-20 mA output?

Yes. AO2000/AO2040 series analyzers typically support 4-20 mA analog outputs, but the available outputs depend on the installed I/O modules.

Do you provide datasheets?

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