The Colorlight SSR-TEMP is a temperature and humidity sensor for monitoring the environment around an LED display installation. It sends readings over RS485 with the Modbus RTU protocol, making it suitable for a compatible monitoring system. The compact unit supports indoor DIN rail, wall, or ceiling mounting.
Key features
- Measures both ambient temperature and relative humidity.
- RS485 communication with a stated distance of up to 1,200 m, subject to cabling and installation conditions.
- Modbus RTU protocol with configurable addresses from 1 to 247.
- 5–12 V DC input and less than 0.1 W average power consumption.
- Standard 5 m cable; DIN rail, indoor wall, or ceiling installation.

Installation and compatibility
Connect the sensor to a compatible RS485/Modbus RTU monitoring interface and provide 5–12 V DC power. Set the sensor address and baud rate to match the host system. Verify the controller’s sensor support and wiring requirements before installation; an RS485 port alone does not establish compatibility. The listed mounting options are for indoor installation.
Frequently asked questions
What does the SSR-TEMP measure?
It measures temperature and relative humidity. The specified ranges are -40 to 120°C and 0–100% RH.
How does it send readings?
It uses RS485 and the Modbus RTU communication protocol. The specified address range is 1–247.
Is it a standalone LED display controller?
No. It is a sensor that supplies environmental readings to a compatible monitoring system.
Conclusion
Choose the SSR-TEMP when a compatible LED display monitoring setup needs temperature and humidity readings over RS485/Modbus RTU. Confirm power, wiring, and host compatibility before ordering.
