Omron E5EC-RR2ASM-810 Digital Temperature Controller
The Omron E5EC-RR2ASM-810 Temperature Controller is a compact and precise Digital Temperature Controller designed for stable, fast-response industrial temperature control. Its 48 × 96 mm design supports a versatile operates on 24 VAC, 50/60 Hz; 24 VDC with an allowable range of 85 to 110% of the power supply voltage , it provides ON/OFF control or 2-PID control (with auto-tuning) for consistent temperature stability. The controller features Relay output 1, Relay output 2, 2 point auxiliary outputs, Digital setting using front panel keys, 11-segment digital display for improved visibility, and Screw Terminal Block wiring for easy panel integration. Manufactured by Omron, part of the Omron Temperature Controller ecosystem within the Omron E5EC Series.

The Omron E5EC-RR2ASM-810 is frequently assessed alongside other units in the Digital Temperature Controllers group because they share comparable sensor inputs, panel depth behaviour, and loop-control characteristics. Engineers often evaluate Omron E5EC-QR2DSM-810 (48 × 96 mm, ON/OFF control or 2-PID control, 24 VAC, 50/60 Hz; 24 VDC, Voltage output, 11-segment digital display), Omron E5EC-CR2DSM-804 (48 × 96 mm, ON/OFF control or 2-PID control, 24 VAC, 50/60 Hz; 24 VDC, Relay output, 11-segment digital display), and Omron E5EC-QX2ABM-800 (48 × 96 mm, ON/OFF control or 2-PID control (with auto-tuning), 100 to 240 VAC, Voltage output, 11-segment digital display) when selecting a controller that fits panel wiring, SSR/relay load stages, and enclosure thermal limits. Reviewing shape, control method, supply voltage class, output structure, and indication style builds a clearer link between field sensors, heater.
