Temperature & Humidity Sensor with 2 C/NC/NO Relay Outputs – RS485 Modbus
🟢 10 in stock - Delivery 1-2 days (more can be ordered)
Monitor temperature and humidity in real time with this professional sensor for building automation, climate control and industrial environments.
Operating voltage: 12~36V DC or 24V AC (±20%)
Operating temperature of the device: -20 – +70 degrees Celsius.
Programming is done directly on the display and alarms via min/max values on separate relays C/NC/NO to other systems such as alarms.
The sensor uses RS485 Modbus-RTU communication and has built-in display for clear reading directly on site.
The robust construction and external sensor make it ideal for server rooms, warehouses, industry, real estate and technical installations where stable environmental monitoring is important.

Temperature & Humidity Sensor with 2 Relay Outputs – RS485 Modbus
This temperature and humidity sensor is designed for installation in alarm systems, building automation and technical monitoring systems where climate changes should be able to trigger alarms or control via relay.
The sensor is also equipped with two separate relay outputs which can be used for different types of climate alarms:
-
Relay 1 – Temperature: activated at set temperature limit value
-
Relay 2 – Humidity: activated at set humidity value
This makes the sensor particularly suitable for installations where temperature or humidity can affect operation, equipment or safety.
The relays can be connected directly to, for example, alarm inputs on central units, control systems, ventilation systems or operational alarms.
The relays have a load capacity of up to 24V/2A or 0.5A at 220V which makes it possible to control external devices or send alarm signals to other systems.
Please note that if you have larger loads, you should not control these directly via the unit's built-in relays, but instead do this via a contactor or an intermediate relay.
Operating voltage: 12~36V DC or 24V AC (±20%)
Operating temperature of the device: -20 – +70 degrees Celsius.
Adapted for alarm installations
The sensor is a practical complement to security and surveillance systems where environmental conditions need to be monitored. Through the two relay outputs, the sensor can be used to create separate alarms for temperature and humidity.
Typical functions in alarm installations:
-
temperature monitoring in server room
-
moisture alarm in technical room or basement
-
climate monitoring in alarm cabinet
-
operational alarm for cooling or ventilation system
-
environmental monitoring in real estate and industry
RS485 Modbus for integration
In addition to the relay outputs, the sensor has RS485 communication with Modbus RTU, which makes it possible to integrate it into building automation, PLC systems or other monitoring platforms.
Temperature and humidity can then be read centrally while the relay outputs are used for local alarms.
Display for local reading
The integrated LCD display shows the current temperature and humidity directly on the sensor. This makes installation, control and service easier as the values can be checked locally without connection to a higher-level system.
Stable measurement in technical environments
The sensor is designed for stable operation in technical installations and measures temperature and relative humidity with high accuracy.
The external sensor provides rapid response to changes in the climate.
