Chromalox C76BF-3000-111-20-AE Temperature Controller

Chromalox C76BF-3000-111-20-AE is a Type J thermocouple input temperature controller with a 0–300°F range. Manufactured by Chromalox, the device accepts Type J thermocouple signals to sense process temperature and provides a controlled output to maintain the setpoint within the specified range. It is intended for integration into industrial heating or processing equipment that relies on Type J sensing for temperature regulation. The model number denotes a specific variant within Chromalox's controller lineup, reflecting its designation as a Type J controller with a 0–300°F operating range. When installing, users configure the setpoint and basic operating parameters to suit the application, ensuring proper thermocouple connection and electrical compatibility with the controller's output stage. The 0–300°F specification identifies the applicable cooling/heating range for the controlled process, making it suitable for low-to-mid temperature operations in facilities that use Type J sensors. As with other Chromalox controllers, this unit is designed to operate as a component within a closed-loop control system, enabling automatic adjustments based on sensor feedback. For accurate results, pair the controller with a Type J thermocouple and verify that the control wiring, power supply, and safety practices conform to applicable standards during installation.
