Amp -Frequency to Voltage Converter Highlights Generic Brand Frequency to Voltage Converter Description: It can convert frequency pulse signal to analog voltage signal, transform 0-1KHz frequency signal to voltage output 0-10V Adjustment frequency can change output voltage, can be applied to interface conversion between PLC and frequency converter or interface pairing control occasions like motion control board and the frequency converter, etc. The adjustment potentiometer can calibrate the relationship between frequency and voltage The signal input port adopts optocoupler isolation, which guarantees good anti-interference ability F/V converter module, the response time is about 0.3 -0.5s. If the frequency is adjusted at the same time with a large margin, a certain response time is required. specification: Working voltage: 13.5V-30V Input frequency range: 0-1kHz Output voltage range: 0-10V Size: approx. 35mm x 33mm x 14mm Instructions VCC: power supply GND: ground F: an input frequency pulse signal GND: input ground VOUT: corresponding voltage output GND: output ground; Common Ground for Modules Connect the operating voltage to VCC and GND. Do not reverse it to avoid damage to the card and the device. Connect the frequency pulse signal to F and there is a corresponding voltage output at VOUT. Input and output corresponding relationship: 100HZ=1V, 1KHZ=10V. If there is a gap in the correspondence between the use, adjust the potentiometer on the board. The accuracy of the module is 1% and it cannot be applied to fields requiring high accuracy. Different frequency input, the output will correspond to a certain voltage. Input pulse level can be 5V, 12V, 24V, series resistor is not needed. But if you enter the signal frequency, the time must be greater than 0.5 seconds If you want to use it with a PLC, it supports NPN. Please make sure there is GND wire If you want to use it with encoder, it needs constant rotation of encoder for more than 0.5s Package includes: Frequency converter module in 5 piece voltage
