Omron E5AC-RX4DSM-008 Digital Temperature Controller

The Omron E5AC-RX4DSM-008 Temperature Controller provides low-voltage digital temperature control with a relay output and four auxiliary functions for industrial process applications. Its DIN 96 × 96 panel design operates from 24 VAC at 50/60 Hz or 24 VDC and receives process temperature information through one input point. ON/OFF and 2-PID control modes support different approaches to thermal regulation, while auto-tuning assists with configuring PID response. A relay output together with four auxiliary outputs allows the controller to coordinate temperature switching with additional system functions. An 11-segment digital display supports monitoring, and screw terminals provide the electrical wiring interface. The E5AC-RX4DSM-008 belongs to the E5AC Series and the wider 24V process temperature controller range within Omron industrial controls.
