Information About E5AX-A20

The E5AX-A20 is a discontinued temperature controller from Omron, engineered for use in industrial process control and thermal regulation systems. It offers PID-based precision temperature management and supports modular I/O configurations via plug-in output units. While it is no longer in production, the E5AX-A20 remains widely available through surplus and refurbished industrial automation suppliers.

Key Features:

  • Omron Engineered: Originally manufactured by Omron for factory automation and process control applications.
  • Dual LED Display: Equipped with 4-digit LED screens for both process value (PV) and setpoint value (SV), providing real-time monitoring.
  • PID Control: Utilizes auto-tuned Proportional-Integral-Derivative control algorithms for stable and responsive thermal regulation.
  • BCD Communication: Supports binary-coded decimal (BCD) communication for integration with digital host systems.
  • 1/4 DIN Mounting: Standard 48×48 mm housing ideal for panel-mount installations in compact or dense environments.
  • Wide Power Range: Operates on 100–240 VAC at 50/60 Hz with 15 VA power consumption, ensuring compatibility across systems.
  • Discontinued Model: Production ceased in 2003, but replacement units remain available in the aftermarket sector.
  • Field Configurable: Supports multiple input types including thermocouples and RTDs, selected via DIP switch settings.
  • Refurbished Availability: Commonly sold by industrial parts vendors in tested and warranty-covered condition.
  • Legacy System Support: Frequently used to maintain or retrofit older process control setups dependent on Omron controllers.

The E5AX-A20 continues to provide reliable temperature regulation in legacy systems requiring standardized displays, modular I/O, and robust PID functionality. Its enduring utility makes it a practical solution for retrofit projects and legacy equipment maintenance.
