E5CSL-RTC

The Omron E5CSL-RTC is a compact and reliable digital temperature controller from the E5CSL Series, designed for basic industrial temperature control applications where accuracy, simplicity, and durability are essential. With its compact 1/15 DIN panel-mount size, it is well suited for space-limited control panels and small automation systems.

This model accepts thermocouple inputs and supports both ON/OFF control and 2-PID control with auto-tuning, allowing flexible temperature regulation based on process needs. The relay control output enables direct switching of heaters and other loads without additional interface devices. Configuration and operation are made simple through digital front-panel keys, enabling quick setup and adjustment.

Powered by a wide-range 100–240 VAC supply, the E5CSL-RTC is built for continuous industrial operation. Additional functions such as temperature input shift, run/stop control, and protection features enhance system reliability and operational safety. It is commonly used in heaters, ovens, small furnaces, and general-purpose industrial control panels.
