During technical comparisons, EJ1N-TC2A-CNB appears alongside Omron Photoelectric Sensor, Sub Zero Temperature Controller and Omron Photoelectric Sensors E3T Series so engineers assess signal types, ingress protection, and ambient tolerances accurately.
Omron EJ1N-TC2A-CNB Modular Temperature Controller
The Omron EJ1N-TC2A-CNB Temperature Controller is a compact and precise Modular Temperature Controller designed for stable, fast-response industrial temperature control. Its Module type design supports a versatile operates on 24 VDC with an allowable range of 85 to 110% of the power supply voltage, it provides ON/OFF or 2-PID control with auto-tuning and self-tuning for consistent temperature stability. The controller features Current output 2-points, , Transistor output 2-points and Screw terminal (M3) wiring for easy panel integration. Manufactured by Omron, part of the Omron Temperature Controller ecosystem within the Omron EJ1N Series.
