Campbell Scientific SDM-AO4 Module Specification

The Campbell Scientific SDM-AO4 module is a sophisticated analog output device designed to enhance data acquisition systems by providing precise control over voltage outputs. This module is engineered to integrate seamlessly with Campbell Scientific dataloggers, expanding their capabilities in environmental monitoring and industrial applications. The SDM-AO4 features four independent analog output channels, each capable of delivering a voltage range from -5 to +5 volts, which allows for the precise simulation of sensor signals or control of external devices.

The module utilizes the Synchronous Device for Measurement (SDM) protocol, enabling up to 16 SDM devices to be connected to a single datalogger, thereby significantly increasing the system's versatility and scalability. Its operational design supports a variety of applications, including actuator control, process simulation, and voltage signal generation, making it ideal for complex data acquisition and control systems.

Each channel on the SDM-AO4 is isolated to prevent interference and ensure signal integrity, a critical feature for maintaining data accuracy in multi-device configurations. The device boasts high-resolution output with 16-bit digital-to-analog conversion, ensuring fine granularity and precision in voltage adjustments. The module is housed in a rugged enclosure suitable for field deployment, withstanding harsh environmental conditions while maintaining reliable performance.

The SDM-AO4's compatibility with a wide range of Campbell Scientific dataloggers, combined with its robust design and high-precision outputs, makes it an essential component for professionals seeking to implement sophisticated environmental and industrial monitoring solutions. Its efficient integration and control capabilities enhance the overall effectiveness of data acquisition systems, enabling accurate data collection and analysis.

Campbell Scientific SDM-AO4 Module F.A.Q.

What is the primary function of the Campbell Scientific SDM-AO4 Module?

The SDM-AO4 module is designed to expand the analog output capability of a Campbell Scientific data logger, providing four independent analog voltage outputs for control applications.
