The Selco S6000.0020 is a robust and reliable temperature controller designed for monitoring and protecting critical machinery such as engines, generators, and industrial equipment. It operates with a Pt100 sensor to accurately measure temperature within a predefined range. When the temperature exceeds the user-adjustable setpoint, the internal relay is activated, triggering an alarm or initiating a shutdown sequence to prevent damage. Featuring clear LED indicators for power and alarm status, the S6000.0020 provides straightforward visual feedback. Its compact design and durable construction make it an ideal solution for demanding applications in marine, industrial, and power generation environments.
