The Selec TC303 Temperature Controller supports a wide temperature range depending on the type of input sensor you connect to it. When using a thermocouple sensor (like type J, K, or T), the Selec TC303 can measure and control temperatures typically from 0°C to 1200°C. If you use an RTD PT100 sensor, the range is generally –199°C to +600°C. This flexibility makes it suitable for both low and high-temperature applications across different industries. You can easily select the input type from the front panel during setup, and the controller automatically adjusts its measurement range accordingly.
The Selec TC303 is designed for accurate and stable control in heating or cooling systems. Its PID and ON/OFF control modes help maintain the desired temperature without frequent overshoots or fluctuations. Because of its wide temperature range, this model is used in ovens, furnaces, packaging sealers, chillers, and industrial heaters. The controller’s 3-digit display allows you to monitor real-time temperature clearly, and the adjustable setpoints make it easy to fine-tune the operation. It supports both relay and SSR outputs, depending on your connection needs.
In short, the Selec TC303 Temperature Controller covers almost all industrial temperature control requirements — from sub-zero cooling systems to high-temperature heating equipment. Whether you’re working with plastic molding, food processing, or laboratory testing, the TC303 provides reliable performance within its broad –199°C to 1200°C operating range.
