Vaisala INDIGO520 A2N9B0NAAN is an industrial measurement transmitter with a capacitive touchscreen display, belonging to the Vaisala Indigo500 Series.

The transmitter supports simultaneous connection of two compatible Vaisala Indigo measurement devices, enabling real-time data visualization, measurement monitoring and communication with industrial automation systems.

Depending on the connected probes, the transmitter supports humidity, temperature, dew point, carbon dioxide, hydrogen peroxide and moisture-in-oil measurement applications.

The Indigo520 provides four configurable analog outputs, two relay outputs, an analog input, Ethernet connectivity and Modbus TCP/IP communication.

The built-in web interface allows users to access measurement data and configure supported transmitter functions remotely.

The IP66-rated metal enclosure supports installation in demanding industrial environments.

Important Technical Notes:

The Indigo520 is a transmitter and display unit, not a standalone measurement probe. Actual measurement parameters, ranges and accuracy depend on the compatible Vaisala probe connected to the transmitter.

The A2N9B0NAAN configuration does not include a barometric pressure module or probe connection cable. Compatible probes and required connection cables must be selected separately.
