Omron E5AC-QQ4DSM-000 Digital Temperature Controller
The Omron E5AC-QQ4DSM-000 Temperature Controller is a compact and precise Digital Temperature Controller designed for stable, fast-response industrial temperature control. Its DIN 96 x 96 design supports a versatile 1 point input for accurate sensing across various temperature applications. Operating 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 or 2-PID control with auto-tuning for consistent temperature stability. The controller features Voltage output (for driving SSR) 1, Voltage output (for driving SSR) 2, 4 point auxiliary outputs, 11-segment digital display that enhances visibility, its Screw terminal block 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-QQ4DSM-000 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-RX4DSM-012 (DIN 96 x 96, ON/OFF or 2-PID control, 24 VAC (50/60 Hz) 24 VDC, Relay output, 11-segment digital display), Omron E5AC-QR2ASM-010 (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), and Omron E5AC-QR4ASM-008 (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) 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.
