E5CSL-QTC

The :contentReference[oaicite:0]{index=0} is a compact and economical digital temperature controller from the E5CSL Series, designed for basic industrial temperature control applications. It features a 1/16 DIN (48 × 48 × 60 mm) panel-mount design and is engineered to deliver stable ON/OFF or 2-PID temperature control with easy front-panel setup.

This controller supports thermocouple input and is equipped with a voltage output for driving solid-state relays (SSR), making it suitable for control of heating elements and other loads where silent switching is advantageous. Built for industrial environments, the unit operates on a 100–240 VAC power supply with an allowable range and includes key functional features such as temperature input shift, run/stop, and protection functions.

The E5CSL-QTC is widely used in heating systems, ovens, small furnaces, packaging equipment, and general automation panels where precise and reliable temperature control is essential.
