Features Suitable for switching API and frequency converter. Signal inputs with optical coupling isolation, which can ensure the ability of anti-interference. The input pulse level is 5V 12V 24V, which can be input directly without series resistor. The frequency of the input signal should maintain more than 0.5 seconds. The pulse signal frequency 0HZ to 10K HZ converts into an analog voltage signal of 0-10V. This module is easy to wire and convenient to use. Description: The pulse signal frequency 0HZ to 10K HZ converts into an analog voltage signal of 0-10V. Can be used to interface the switching between the API and the frequency inverter, or interface pairing, such as the pairing of motion control board and inverter control. Specification: Output current: 5MA Voltage: 0-10 V. Input pulse level: 5V 12V 24V Frequency: 0 to 10KHZ Size: approx. 4.5 x 4.5 cm/1.77 x 1.77 inches. Weight: 18 g Quantity: 1 piece. Matching relationship: When the F/V with the resistance transferred to an intermediate value, F/v corresponding to the next relationship, 100HZ = 0.1V, the accuracy is 1%. It cannot reach 2 digits after the decimal point if a relatively high accuracy of the occasion is not enough. 0.1 V = 100 Hz. 500Hz = 0.5V. 1 kHz = 1 V. 2 kHz = 2 V. 3 kHz = 3 V. 4 kHz = 4 V. 5 kHz = 5 V. 6 kHz = 6 V. 7 kHz = 7 V. 8 kHz = 8 V. 9 kHz = 9 V. 10 kHz = 10 V. Each 0.1V DC match between frequency 100HZ. When matching is allowed, can be corrected to fit the potentiometer of the card. Package list: 1 x Frequency to Voltage Converter Package List
