Features: 1. The multi-turn potentiometer on the board is used to calibrate the frequency and output voltage. 2. The signal input is isolated by diaphragm. Guaranteed anti-interference ability. 3. If you need to use PLC, you can use common anode wiring mode, the power supply is powered by 24V, PUL+ pulse is connected to power supply, and PUL- is connected to signal pulse. 4. If you need to use the encoder, the encoder should be rotated at a constant speed for more than 0.5 seconds. 5. Frequency to voltage module, response time is about 0.3-0.5 seconds. 6. The power input has anti-reverse function Specification: Condition: 100% Brand new Item Type: Converter Module Model: GFV-1KHz5V Function: Input 0-1KHz frequency is converted to 0-5V Model: GFV-1KHz10V Function: Input 0-1KHz frequency is converted to 0-10V A frequency pulse signal of about 0 Hz to 1 kHz is converted into an analog voltage signal of 0-5/10V. Can be used for interface conversion between PLC and inverter. Or the motion control card and the inverter and other interfaces match the control occasion. Output current: 5MA The output voltage is 0-10V or 0-5V, and there is also a jump stitch on the board. Size: Approx. 5 x 4.5 x 1.7cm / 2 x 1.8 x 0.7in Optional Style: GFV-1KHz5V, GFV-1KHz10V Frequency GFV-1KHz5V Output Voltage GFV-1KHz10V Output Voltage 100Hz 0.5V 1V 500Hz 2.5V 5V 1KHz 5V 10V Package List: 1 x Voltage Frequency Converter Module Identification Wiring: 1. V+: Power input is positive 2. GND: Power input negative (common ground wire) 3. PUL-: pulse frequency input negative, signal pulse when common anode, grounding wire when common cathode 4. PUL+: The pulse frequency input is positive, the power supply is positive when the common anode is connected, and the signal pulse is connected when the common cathode is connected. 5. GND: Negative voltage output (ground wire connection) 6. OUT: is the analog voltage 0-10V or 0-5V output 1、The multi-turn potentiometer on the board is used to calibrate the frequency and output voltage. 2、The signal input is isolated by diaphragm.
