Omron E5AC-QX3ASM-800 Digital Temperature Controller
The Omron E5AC-QX3ASM-800 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 1 point input for accurate sensing across various temperature applications. Operating on 100 to 240 VAC, 50/60 Hz with an allowable range of 85% to 110% of rated supply voltage , it provides ON/OFF or 2-PID control with auto-tuning for consistent temperature stability. The controller features Voltage output, 3 auxiliary outputs, 11-segment digital display that enhances visibility, its Push-In Plus Terminal wiring system simplifies installation and reduces panel wiring time. Manufactured by Omron, part of the Omron Temperature Controller range within the Omron E5AC Series.

The Omron E5AC-QX3ASM-800 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 E5AC-QR2ASM-000 (DIN 96 x 96, ON/OFF or 2-PID control, 100 to 240 VAC (50/60 Hz), Voltage output (for driving SSR), 11-segment digital display), Omron E5AC-RR2DSM-012 (DIN 96 x 96, ON/OFF or 2-PID control, 24 VAC (50/60 Hz) 24 VDC, Relay output, 11-segment digital display), and Omron E5AC-QX2DSM-012 (DIN 96 x 96, ON/OFF or 2-PID control, 24 VAC (50/60 Hz) 24 VDC, Voltage output (for driving SSR), 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.
