Modbus Capable Sensors with S+S Technology

Smart Facility Automation for Central Energy Management

In view of rapidly rising energy costs, centralised recording, monitoring
and control of power consumption is of increasing importance in facility
management. Our Modbus interconnective measuring transducers for
temperature, humidity and pressures as well as VOC, CO2 and particulate
matter can help you improve the overall energy efficiency of buildings and
save a lot of money.

Application Areas of Modbus Sensors

Facility automation in industrial and commercial buildings, central energy management in public and private facilities, including hospitals, administration centres, schools and museums, as well as acquisition and control of temperature, humidity and pressure parameters in areas with difficult access


  • Widely used fieldbus standard in facility management
  • Non-proprietary communication protocol
  • Proven S+S sensor technology

powerIO® System for Facility Automation

The powerIO® system enables a more efficient control, better monitoring and operational management than previous, conventional solutions. And all of this independent of control system suppliers. The imodular technology offers high compatibility with all sensors and actuators from leading manufacturers, and can be extended to support any common protocol. Its basic design uses three modular components: powerIO®-Box, powerIO®-Line and powerIO®-App

Assured precision

All devices are developed, manufactured and tested according to the latest criteria. Each sensor is precisely re-adjustable using offset potentiometers. Take advantage of our experience, our development, manufacturing, and product know-how, and order these products directly from the manufacturer.


Broad spectrum

All Modbus sensors for S+S temperature, humidity, pressure and air quality sensors are designed to be multifunctional. This reduces the diversity of types and expands their possible applications. Thanks to microprocessor technology, almost any measuring range can be represented, including customer specifications.

How our Modbus sensors benefit you:

  • Widely used bus standard
  • Vendor-neutral communication protocol
  • Proven S+S sensor technology
  • Reliable and fast data transmission
  • Decades of secure data exchange
  • World renowned system for our Modbus sensors
  • S+S quality assurance

Multifunctional Modbus measuring transducers

All of our Modbus sensors, THERMAGARD® temperature sensors, HYGRASGARD® humidity sensors, PREMASGARD® pressure sensors and AERASGARD® air quality sensors are designed to be multifunctional, with combined sensor technology and switchable measuring ranges. This reduces the required diversity of types with extended application possibilities. Thanks to microprocessor technology, almost any measuring range can be represented, including customer specifications. The outstanding features of the S+S Modbus devices include galvanic isolation of the RS485 interface as well as simple setting of the bus parameters and bus address in the de-energised state via DIP switches. For versions with a display, its 7/14-segment and 40-dot matrix areas can be configured without restrictions.

Versatile room controller with bus connection

S+S RYMASKON® room control units enable monitoring, control and regulation of the indoor climate in residential and office buildings, hotels and conference centres etc. on site and via Modbus according to needs. They provide the required measured values for heating and air conditioning systems, blowers and sun protection equipment. Modbus sensors for relative humidity and CO2 are also available. All of these elegant room controllers have a colour touch screen for user-friendly operation using intuitive symbols. Preconfigured operating modes such as Comfort, ECO, Boost, Holiday or Frost Protection simplify the setting.
