Omron E5AC-QQ2DSM-012 Digital Temperature Controller

The Omron E5AC-QQ2DSM-012 Temperature Controller provides temperature regulation through two SSR-driving voltage outputs while operating from a low-voltage control supply. It accepts 24 VAC at 50/60 Hz or 24 VDC and uses a single temperature input within its DIN 96 × 96 panel-mounted design. ON/OFF or 2-PID control can regulate the thermal process, with auto-tuning assisting the configuration of PID parameters. Its two voltage outputs for driving SSRs and two auxiliary outputs connect the controller with external switching devices and additional process functions. The 11-segment digital display supports operator monitoring, while screw terminal connections provide the electrical interface. The E5AC-QQ2DSM-012 forms part of the E5AC Series and the broader 24V digital temperature controller range within Omron process automation products.
