The Allen Bradley 1771-HR is an analog input module of the Rockwell Automation PLC-5 series. It is responsible for converting thermocouple signals into digital signals for use by the PLC. It is compatible with various types such as J, K, and T, and is particularly suitable for equipment requiring precise temperature control, such as injection molding machines and furnaces. Hanyite Automation Technology, as a professional supplier, has original and genuine products in stock. If you wish to purchase, we can arrange the shipment at any time.
Allen Bradley 1771-HR is a thermocouple/millivolt input module for the PLC-5 series. Its main advantage lies in enabling the control system to directly read and process temperature signals. With it, you no longer need to purchase an additional temperature transmitter separately. This directly saves you hardware costs and installation space in the control cabinet. It can accurately convert the weak analog signals collected by the on-site sensors into digital signals and transmit them to the PLC, allowing you to achieve more precise and efficient temperature control during the production process.
This module is of extremely high quality and is a typical industrial-grade product. It adopts a robust industrial design and the circuit board has undergone special protective treatment, with extremely strong anti-interference capabilities. Even in an environment with large voltage fluctuations and numerous electromagnetic interferences in the factory, it can maintain stable operation for a long time, is not prone to failure, and the measurement data remains very accurate. Its durability is particularly strong, ensuring that your production line has fewer malfunctions.
Since Allen Bradley 1771-HR is an input module plugged into the PLC rack and does not have a screen on its own, the human-machine interaction function is not directly operated on it. Operators interact through the upper computer or touch screen (HMI) connected to the PLC. The 1771-HR transmits temperature data to the PLC, which processes it and then displays it on the screen. Operators can directly see the real-time temperature values and alarm information. If parameters need to be adjusted, it is also operated on the screen, and the instructions will eventually be sent to this module for execution. It works very smoothly.
