EJ1N-TC2A-QNHB

The Omron EJ1N-TC2A-QNHB is a modular temperature controller specifically crafted for efficient temperature management in diverse applications. This device is designed with M3 screw terminal connections for easy wiring. Weighing only 0.40 lbs, it features a nominal operating voltage of 24 VDC, making it compatible with standard automation systems. The unit is rated at IP20 for the rear case, providing adequate protection in most installations, while the terminals have an IP00 rating, indicating the need for caution in environmental exposure.

This controller is suitable for use in environments ranging from -10°C to 55°C during operation, and it can be stored in conditions between -25°C and 65°C. With a relative humidity tolerance of 25% to 85%, condensation must be avoided to ensure reliable performance. The maximum power consumption is rated at 4 watts.

The linear analog input options are varied, including configurations for 0 to 10 volts, 0 to 20 mA, 0 to 5 volts, 1 to 5 volts, and 4 to 20 mA, facilitating integration with different sensors and systems. Additionally, the unit supports two event inputs, allowing for programmable responses to specific conditions. Its indication accuracy is noted to be ±0.5% of the process variable or ±1°C, whichever is greater, along with an additional ±1 digit for precise readouts.

For communication purposes, the EJ1N-TC2A-QNHB is equipped with an RS-485 port, enabling connection with networked devices and facilitating easy data transfer in controller setups. This combination of features makes it an efficient choice for temperature control in various industrial settings.
