Dyacon MS‑120™ is a cable‑connected weather station. It connects to computers and automation controllers through the onboard Modbus RTU (RS-485) port.
MS-120™ includes a control module (data logger), wind sensor, and temperature-pressure-humidity sensor. Options such as a rain gauge, solar sensor, or soil moisture sensor can be added at any time to meet the user’s changing needs. MS-120 can also be upgraded in the field with either cell phone or WiFi wireless modules.
MS‑120™ can serve as a data logger or be wired to programmable logic controllers (PLCs) through the Modbus RTU slave port. The Modbus RTU port can also be connected to a personal computer with a simple RS485-to-USB converter. A USB device port provides an interface to a Windows computer for configuration and data log retrieval.
MS‑120™ comes preconfigured for easy setup; no programming is required. The weather station can be powered with 12 VDC to 24 VDC.
Add Dyacon Tripod-1 for permanent or portable installations.

MS‑120™ is shipped with the control module, wind sensor (WSD‑1), air sensor (TPH‑1), and mounting hardware suitable for mounting onto a pole or flat surface.
MS‑120 includes a Modbus RS‑485 slave port. The robust characteristics of RS‑485 allow for long cable runs. CAT‑5 cable is an excellent choice for cable runs of over 1,000 ft (300 m).
Adding Dyacon Tripod‑1 (optional add-on) facilitates optimal weather station portability and installation flexibility.
Dyacon MS‑120 is unique, expandable, and flexible.
MS‑120 uses the same control module hardware (data logger) as other Dyacon MS‑1xx weather stations. As such, optional add-ons such as a rain gauge, solar sensor, soil moisture probe, and soil temperature probe are available at any time.
The weather station can be converted to a solar-powered station with the addition of a solar module and battery, which can be installed in the field.
Brackets and hardware are included for mounting the components onto 3/4” to 2” pipe or a flat surface.
Separate wind and air sensors allow for instruments to be positioned at conventional elevations or as required by the application.
The control module is equipped with both a USB device and Modbus slave ports for connecting to data hosting equipment, such as PCs or programmable logic controllers (PLCs).
Dyacon MS‑120 is designed to be easily installed and maintained by the user. All sensors shipped with the unit are preconfigured and tested prior to shipment. Full instructions are available to enable setup to be done by the user without technical support.
Weather station MS‑120 includes a 12 V output for the Smart-Fan aspirated radiation shield, which improves temperature accuracy in sunny conditions. (Refer to the data sheet for a description of I/O and sensors.)
USB to Modbus-RTU
