Temperature control is crucial in various applications, from household appliances to industrial machinery. A Temperature Control Relay (TCR) plays a vital role in maintaining the desired temperature in these systems by regulating heating or cooling devices. This article will explore the basic concept of a Temperature Control Relay, its functions, and its applications across different industries.

What is a Temperature Control Relay? A Temperature Control Relay is an electromechanical device designed to control temperature by switching heating or cooling devices on or off based on a preset temperature range. It works by receiving input from a temperature sensor, such as a thermistor or thermocouple, which measures the ambient temperature. When the temperature reaches a certain threshold, the relay activates or deactivates the connected devices accordingly. This process ensures that systems maintain the desired temperature and operate efficiently. How Does a Temperature Control Relay Work?
