The UFC721BE101 Digital Input Module is a device used to connect external mechanical contacts and electronic digital sensors, such as two wire photoelectric switches and proximity switches. The main function of this module is to convert the feedback of external digital signals transmitted from the site into the internal signal level of the PLC. RC filtering circuits are usually installed in input circuits to prevent erroneous input signals caused by input contact jitter or external interference pulses. In addition, the digital input module also has functions such as jitter reduction, signal frequency calculation, and edge counting. In industrial automation measurement and control systems, the UFC721BE101 digital input module plays an important role. It can convert external digital signals into internal signals that can be recognized by PLC, thereby achieving monitoring and control of external equipment or environment. At the same time, the digital input module also has isolation and power amplification functions to protect PLCs and other equipment from electrical noise and interference. It should be noted that the selection and use of the UFC721BE101 digital input module should be determined based on specific industrial automation system and application requirements. When selecting a module, it is necessary to consider its input signal type, input range, resolution, response time and other parameters, and ensure that it can be compatible and cooperate with PLC and other devices. Meanwhile, during installation and use, it is also necessary to follow the relevant instructions and specifications to ensure the stability and reliability of the system.
