The Omron E5CSL-QP Temperature Controller is a compact 1/16 DIN controller designed for temperature regulation through an SSR-driving voltage output. Its 48 × 48 × 60 mm construction operates from 100 to 240 VAC at 50/60 Hz, with an allowable supply range of 85% to 110% of rated voltage. ON/OFF or 2-PID control with auto-tuning provides different methods for managing industrial thermal processes. The voltage output for driving an SSR provides the primary switching signal for the connected control circuit. Front-panel keys support digital configuration, while a 7-segment display provides operating information. The E5CSL-QP forms part of the E5CSL Series under the SSR temperature controller range offered by Omron control equipment.
