Campbell Scientific LLAC4 Module Specification

The Campbell Scientific LLAC4 Module is a specialized interface designed for seamless integration with dataloggers, facilitating the connection of low-level AC sine wave output sensors. This module extends the capability of dataloggers to accurately capture and process signals from sensors that produce low-level AC outputs, such as magnetic flow meters and other similar devices. The LLAC4 is engineered to convert these AC signals into digital signals that are compatible with the dataloggers, ensuring precise data collection and analysis.

The LLAC4 Module features four independent channels, each capable of handling low-level AC signals. It is adept at managing input frequencies ranging from 1 Hz to 20 kHz, with an AC input range of ±20 mV to ±2.5 V, making it versatile for various sensor types. The module supports both single-ended and differential input configurations, offering flexibility in sensor connection. The LLAC4 is powered directly from the datalogger, eliminating the need for an external power source, thus simplifying deployment in remote or distributed sensing environments.

The module’s robust design ensures reliable performance even in harsh environmental conditions, making it suitable for a wide range of applications including hydrology, meteorology, and environmental monitoring. Its compatibility with Campbell Scientific dataloggers guarantees seamless data integration and processing, providing users with accurate and reliable data for analysis. The LLAC4 Module is an essential component for users needing to connect low-level AC output sensors to their data acquisition systems, enhancing the functionality and application range of Campbell Scientific’s datalogging solutions.
