Description:

• LC_F2V is a module which can transform the frequency pulse signal into analog voltage signal. It can transform 0-1KHz frequency signal into 0-10V voltage output.
• Adjusting frequency can change output voltage, and it can be applied to interface conversion between PLC and frequency converter or sports control card and frequency converter interface matching control.

Features:

• Operating Voltage: 13.5-30V
• Input Frequency Range: 0-1KHz
• Output voltage fine tuning
• Adjusting potentiometer can calibrate the relationships between frequency and voltage
• Signal input port adopts optocoupler isolation, it guarantees good anti-interference capacity
• F/V converter module, response time is 0.3-0.5s. If you want to adjust frequency by a large margin, it needs some time to response
• Working temperature:-25~85℃

Interface definition:

• VCC: operating power supply
• GND: power ground
• F: input frequency pulse signal
• GND: input ground
• VOUT: output corresponding voltage
• GND: output ground

Note:

• Input different frequency, output will correspond to certain voltage
• Input pulse level can be 5V, 12V, 24V, you don’t have to serial connect resistor. But if you input signal frequency, the time should be more than 0.5s
• If you want to use it with PLC, it supports NPN. Please make sure that there is GND wire
• If you want to use it with encoder, it requires the encoder constant speed rotating for more than 0.5s

Operating Introduction:

• Connect the operating voltage with VCC and GND, and they cannot be reversely connected
• Connect frequency pulse signal with F, then there will be corresponding voltage output in the VOUT port Input and output corresponding relationship: 100Hz=1V; 1KHz=10V
• The module precision is 1%, and it cannot be applied to fields which has high demanding of precision
