The TH104IoT V6.1 is a temperature and protection controller designed to monitor and protect transformers, motors, generators, and other industrial equipment subject to excessive heating. With four inputs for PT100 RTD sensors, it allows simultaneous and individual temperature monitoring, with programmable alarms and automatic relay activation.

This equipment is designed for use in critical industrial environments, offering reliability and measurement accuracy. Its unique feature is native IoT connectivity via Wi-Fi, allowing remote access through the iot.thermtronic.net platform, in addition to the standard Modbus RS485 interface.

The front panel features an intuitive, multilingual graphic display (Portuguese, Spanish, and English), simple navigation, status animations, and tactile operation buttons. Key features include:

– Real-time temperature display (HOT, SCAN, MAN, TMAX modes)
– Temperature alarms (ALARM) and emergency shutdown (TRIP) with dedicated relays
– Fault relay for automatic detection of damaged probes (FAULT)
– Intelligent ventilation control with two relays (FAN1 and FAN2) and programmable hysteresis
– Manual relay testing via front panel
– Digital anti-noise filter to prevent improper operation
– Remote configuration and operation via web interface or free Modbus software for Windows

It is also possible to configure the Wi-Fi network directly from the equipment by connecting to it via IP (192.168.1.1) to make network adjustments, device ID, and user linking on the IoT platform.
