The S330 / S331 Data Logger and Display provides a universal solution for displaying and recording all relevant parameter of a compressed air system. This includes flow, dew point, pressure, temperature, power consumption, compressor status, and so on. The device offers a powerful yet cost-efficient data logger and display solution for optimal and reliable management and monitoring of your compressed air system.

S331 Compact Version: Central Unit for Your System

The Compact Version of the S331 Data Logger is used to gather and collect measurement data of various field devices. It acts as the central unit where all measurement data is safely stored and visualized. The digital communication outputs expand the S331 to not only be a display and data logger, but also a gateway to connect to IIoT services and to modern software solutions.

S331 Flex Version: More Power and Larger Internal Wiring Space

The S331 Flex Version, a size upgrade from the S331 Compact Version, features an improved hardware design for greater stability and reliability. In addition, the larger housing offers more space for internal wiring and more power for connected sensors. It retains all the technical specifications of the S331 Compact Version and acts as a central data hub, efficiently collecting and organizing measurement data from multiple field devices.

Various Connection Options

The S330 / S331 includes digital inputs for SUTO SDI sensors and Modbus/RTU sensors. To connect the Modbus/RTU sensors properly on an RS 485 bus system, it’s recommended to daisy-chain the sensors to one of the inputs. For this purpose, SUTO offers a RS 485 splitter to simplify the connection. Through this method, users can add up to 16 sensors to the master input, making it most versatile and allowing to monitor whole plants with a single data logger (Additional power supplies for field devices might be necessary).

Connect Third-Party Sensors and Field Device Support

By relying on the industry standard protocol Modbus/RTU, the S330 / S331 supports third-party sensors to be easily integrated into the monitoring system. Field devices can be easily set up using the configuration software, allowing to add a third-party sensor within seconds. All connected sensor data can be logged to the internal memory. This can be used for virtual channel calculations. All real-time values are also forwarded to connected software and monitoring solutions.

Collect Your Sensor Data for Further Analysis

Through the free SUTO S4A software, recordings are downloaded to the PC via USB, LAN or wirelessly using the LTE/4G Modem. The basic analysis can be done in S4M. For more sophisticated compressor analysis, the SUTO CAA software (incl. with the S551) offers many advanced features such as: Performance statistics of compressors like efficiency, air delivery, load/unload cycles as well as leakage analysis, report generation and more.
