RN 400 Temperature Humidity Cloud Data Logger

RN400-T2TS Thermocouple Temperature Data Logger via WiFi is designed to measure 4Ch Thermocouple (K,J,T,N,S,E,B,R ) sensor signal and transfer them to the destination via WiFi connection. The destination would be an information system such as public cloud, local server and even PC. For high level security, it supports up to WPA2 Enterprise protocol. In addition to WiFi, RN400-T2TS can send the measured data to other traditional industrial devices such as PLC, industrial recorder and others through RS485 output. Premium RN400 T2 series have IP65 for protection, OLED screen for cold outdoor, F-RAM memory for instant backup and
micro-SD card for CSV backup

Application Note

RN400-T2TS Thermocouple Data Logger is designed for centralized temperature monitoring in industrial, laboratory, and utility environments. It supports up to 4 thermocouple input channels, including types K, J, T, N, S, E, B, and R, enabling accurate and reliable multi-point temperature measurement.

The device collects real-time temperature data and transmits it to public cloud platforms, local servers, or PCs for comprehensive monitoring and control. It is well-suited for integration with big data and analytics systems, providing continuous and precise temperature inputs for predictive maintenance, process optimization, and performance analysis.

The RN400-T2TS also enhances operational safety by enabling remote alert systems that trigger alarms and notifications when temperature values exceed predefined limits. This ensures timely intervention, improved quality control, and efficient system operation.
