The universal S330 / S331 display and data logger is a powerful yet cost‑efficient solution for displaying and recording all relevant parameters of a compressed air system: flow rate, dew point, pressure, temperature, power consumption, compressor status, and other values. The device ensures reliable monitoring and optimal management of the pneumatic system.
The device is equipped with digital inputs for SUTO SDI sensors and Modbus/RTU sensors. For proper connection via an RS‑485 bus system, daisy‑chaining of the sensors is recommended – SUTO offers an RS‑485 splitter to simplify the wiring. In this way, up to 16 sensors can be connected to a single master input, allowing entire plants to be monitored with one data logger (additional power supplies for field devices might be necessary).
The analog input option allows connection of 0/4…20 mA, 0…10 V, and pulse signals. When more analog sensors need to be connected, an Analog‑Modbus/RTU converter module can be easily added, allowing another 8 analog sensors to be connected. This makes the S330 / S331 a highly versatile solution for integrating existing field hardware.
Due to the industry‑standard Modbus/RTU protocol, third‑party sensors can be easily integrated into the monitoring system. Field devices can be set up within seconds using the configuration software. All data is logged to the internal memory, can be used for virtual channel calculations, and real‑time values are forwarded to connected systems.
By connecting a 4G/LTE modem to the designated M12 port, remote monitoring is possible via the free SUTO S4A software. Recordings are downloaded to a PC via USB, LAN, or wirelessly using the modem. Basic analysis can be performed with S4A. For more sophisticated compressor diagnostics, the CAA software (included with S551) offers many advanced features such as:
The 5″ color touch screen allows up to 4 sensors to be viewed on one page with page scrolling. The built‑in graphic analyzer helps identify abnormalities and problems instantly. For detailed analysis, the use of SUTO S4A software is recommended.
The S330 / S331 is not only a display and data logger but also a central unit for collecting, visualizing, and forwarding measurement data. The device can be easily scaled to meet growing plant requirements and ensures full transparency of all processes within the compressed air system.
Modifications
Compact Version
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.
Supply and Glands
Installation Options
The S330 / S331 Compact Version comes in a compact design which can be panel mounted or ordered with a wall casing.

Flex Version
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.
Supply and Glands
Installation Options
The S330 / S331 Flex Version comes in a rugged wall casing and offers a bigger power supply to the sensors.

Applications
The S331 Display and 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 are not making it a display and data logger, but also a gateway to connect to IIoT services, as well as to connect it to modern software solutions
