OMRON: E5AR Series Programmable Digital Controller

August 5, 2025
E5AR Series Temperature Controller: Fast, Accurate & Customizable to Applications Specific Needs
The E5-R Series provides you with high-accuracy inputs (0.01°C for Pt100) and a 50ms sample and control cycle for all four loops. Its unique Disturbance Overshoot Reduction Adjustment ensures solid, robust control. The R-series can host multiple loops in one unit, The E5ER 2-loops and E5AR 4-loops maximum.
Features
- Easy and clear read-out thanks to bright liquid Crystal Display
- Exceptional versatility – multi-loop control, cascade control, and valve control
- Easy integration with DeviceNet, Profibus or Modbus
- SV programmer optional, 32 programs with up to 256 segments
- A short sampling period of 50 ms enables use in applications requiring high-speed response
- PV, SP, and MV data is displayed simultaneously in a 3-row, negative LCD display with a backlight
- Multiloop control, cascade control, and proportional control are possible with a single Controller
- Equipped with calculation functions as a standard (e.g., square root calculation and broken-line approximation)
- Data setting and monitoring can be performed without special programming
- When using models with CompoWay/F communications, initial settings can be downloaded, and settings can be masked using Support Software (CX-Thermo version 4.0 or higher)

Applications
Mixing Two Flows: Ratio Control
- Used in applications where a secondary flow needs to be mixed in an exact ratio to the main flow, as in colouring paint, mixing yoghurt with jam and chloride with water.
Controlling a Processing Vessel
- In a fermentor, tight control over all the parameters such as temperature, pH, level and/or pressure is essential for a good product.
Temperature & Pressure Interaction in an Autoclave
- Sterilizing products at high temperatures under pressure demands a fast and accurate controller like the E5-R series.
