Omron E5AC-CX4ASM-004 Digital Temperature Controller

The Omron E5AC-CX4ASM-004 Temperature Controller provides digital temperature control with multiple auxiliary outputs for integration into industrial control systems. Its DIN 96 × 96 panel format accommodates one temperature input, and the controller operates from 100 to 240 VAC at 50/60 Hz within the specified allowable supply range. ON/OFF and 2-PID control modes support different thermal processes, while auto-tuning assists with PID parameter adjustment. A linear current output together with four auxiliary outputs allows the controller to coordinate its temperature regulation function with additional control or signaling requirements. The 11-segment digital display supports process monitoring, and screw terminals provide the panel wiring interface. The E5AC-CX4ASM-004 belongs to the E5AC Series and connects to the broader industrial temperature control range within Omron automation products.
