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.
S330: Display Solution
The S330 is a simple and easy-to-install display device with a high resolution 5” graphic display. This allows an easy operation where details are much sharper shown compared to many of the smaller low-resolution displays.
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).
S331 Compact Version: Your Central Data Hub, Compact and Efficient
S331 Flex Version: Enhanced Sensor Power Supply, Larger Internal Wiring Space
The universal display and data logger can display and record all relevant parameters (Flow, consumption, dew point, pressure, temperature, power consumption, compressor status etc.) in a compressed air system.
