1This F/V Module Can put 0-10Khz frequency pulse signal into 0-10V Analog voltage signal 2Can be used to Convert interface between PLC and frequency, Or movement control card and converter interface matching control occasions. 3Input pulse level is 3.3v, 5V, 24V. There are jump pin on the board for selection, without any resistance. 4Power input has anti- reverse connect function, safe to use 5Output voltage can be minute adjustment, can adjust the Potentiometer to calibration the frequency and voltage Linear relationship Features: This F/V Module Can put 0-10Khz frequency pulse signal into 0-10V Analog voltage signal Can be used to Convert interface between PLC and frequency, Or movement control card and converter interface matching control occasions. Input pulse level is 3.3v, 5V, 24V. There are jump pin on the board for selection, without any resistance. Power input has anti- reverse connect function, safe to use Output voltage can be minute adjustment, can adjust the Potentiometer to calibration the frequency and voltage Linear relationship lf matched with the encoder, the encoder constant speed continues to turn more than 0.5 seconds. lf you need matched with PLC, support of NPN. It must be ground. Signal input with optical coupling isolation, to ensure anti-jamming capability. Frequency - to - voltage module, response time is about 0.3-0.5 seconds.
