Omron Electronics has extended its line of proven E5CN series 1/16 DIN size temperature and process controllers with advanced E5CN-H models that provide OEM machine builders with high-speed response, higher resolution and accuracy than standard models, and a wider range for performance customization to meet project requirements, including logic operations and preventive maintenance functions. The advanced functions, including password protected settings and customizable menus, are accessed via CX-Thermo software to ensure the highest level of security. The compact panel-mount controller’s universal inputs for temperature and analog processes, selection of 13 alarm types and 3-color changing display to indicate status enable machine builders to use one model to satisfy the needs of many projects and lower design, purchasing, programming and stocking costs. 

The E5CN-H models offer a fast 60 ms sampling period which allows more precise heater control in rapidly changing, disturbance-sensitive applications. With accuracy of ±0.1% of preset value (PV) for thermocouple and RTD inputs and ±0.1% full scale for analog inputs, the 2-PID control delivers exact control and stability with fast reaction speed. Time saving auto-tuning in E5CN series is considered one 
The five-digit display with 0.01 degrees Celsius display resolution on E5CN-H models shows both PV and SV at a glance and can be preprogrammed so that it changes color (red to green to orange) in response to an alarm, a preset value, or when values vary outside a preset threshold. In a packaging application, the display change can alert plant floor staff that a heater has burned out in a form/fill/seal machine and detect a bad sealing situation before it turns into a high waste situation. The display can also be set to alternate between PV/SV-status and temperature controller status.
