Manufacturer: Rockwell Automation
Brand: Alan Bradley
Part Number/Catalog number: 1756-OF8HK
Series: ControlLogix
Module type: HART analog output module
The 1756-OF8HK HART analog output module is a module that combines the HART communication protocol and analog output function. HART (Highway Addressable Remote Transducer) is a digital communication protocol used primarily in the field of industrial automation. It allows two-way communication and is compatible with traditional 4-20mA analog signals. HART protocol uses the method of carrier superposition to transmit digital signal and analog signal simultaneously on the analog signal line.
The 1756-OF8HK analog output module drives the hardware output and related data path, selects the current set value according to the operation mode, and can also reverse and provide the result to the hardware output or software output as required. In the industrial automation system, the analog output module can receive the digital signal from the digital signal processing or control system, and convert it into a continuous analog signal in order to control the operating state of the external equipment.
Therefore, the 1756-OF8HK HART analog output module not only has the basic function of analog output module, but also has the characteristics of HART communication protocol. It can convert digital signal to analog signal for output, and supports HART communication protocol to realize communication and data transmission with remote monitoring system. This makes HART analog output module have a wide application prospect in the field of industrial automation.
Specifically, the 1756-OF8HK HART analog output module can be used for signal conversion and communication of various sensors and actuators. It can convert the analog signal collected by the sensor into digital signal for processing, and convert the digital signal after processing into analog signal output to the actuator, so as to realize the precise control of the equipment. At the same time, through the HART communication protocol, the module can also communicate with the remote monitoring system to realize the remote transmission and monitoring of data.
Overall, the 1756-OF8HK HART analog output module is a powerful and widely used industrial automation component that can meet the needs of a variety of complex application scenarios.
