The OMRON E5CN-R2T is a high-performance, 1/16 DIN size digital temperature controller renowned for its precision, versatility, and reliability. Part of OMRON’s E5CN series, this panel-mount controller provides advanced PID control for a wide array of industrial heating and cooling applications. It features an 11-segment dual-display for clear visibility, a robust design, and a comprehensive set of functions that simplify installation and operation.
Key Features & Benefits
-
High Accuracy & Performance: Delivers exceptional control with a thermocouple input accuracy of ±0.3% of PV and a fast 250ms sampling period. Some upgraded models offer sampling periods as fast as 60ms, ensuring precise regulation in demanding applications.
-
Versatile Universal Input:Â A single controller accepts multiple sensor inputs, including thermocouples (K, J, T, etc.), platinum resistance thermometers (Pt100, JPt100), and analog signals (4-20mA, 1-5V). This flexibility reduces model variety and simplifies inventory.
-
Easy-to-Use 11-Segment Display:Â The 5-digit, 3-color changing display (red, green, yellow) shows both Process Value (PV) and Set Value (SV) simultaneously. It can be configured to change color based on status, such as an alarm condition, allowing for instant visual monitoring from a distance.
-
Advanced Control & Diagnostics:Â Features 2-PID control with auto-tuning for optimal performance. It includes preventive maintenance functions like a control output ON/OFF counter to predict the lifespan of internal relays, reducing unexpected downtime.
-
Compact Design:Â Its 48 x 48mm (1/16 DIN) size makes it ideal for space-constrained panel installations.
