Description:_x000D_ The frequency of the pulse signal 0HZ to 10KHZ converts into an analog voltage signal of 0-10V. Can be used to interface switching between the PLC and the frequency converter, or interface matching such as the matching of motion control card and inverter control._x000D_ _x000D_ Features:_x000D_ _x000D_ Input pulse level is 5V 12V 24V, which can be directly entered without serial resistor. The input signal frequency must maintain more than 0.5 seconds. _x000D_ The frequency of the pulse signal 0HZ to 10KHZ converts into an analog voltage signal of 0-10V. _x000D_ Suitable for the switching of the PLC and the frequency converter. _x000D_ This module is easy to wire and convenient to use. _x000D_ Signal inputs with optical coupling isolation, which can ensure that the capability of anti-interfence. _x000D_ _x000D_ Specification:_x000D_ Output current: 5MA_x000D_ Voltage: 0-10V_x000D_ Input pulse level: 5V 12V 24V_x000D_ Frequency: 0 to 10KHZ_x000D_ Size: Approx. 4.5 x 4.5cm / 1.77 x 1.77inch_x000D_ Weight: 18g_x000D_ Quantity: 1pc_x000D_ _x000D_ Use:_x000D_ _x000D_ Multi-circle potentiometer board is used to calibrate the correspondence of the frequency and voltage. _x000D_ Input supply voltage range of 12-30V DC.(The voltage of 15-24V is recommended) _x000D_ When the electricity level is 12V, the power supply voltage can NOT be 12V. It's better more than 15V. When the electricity level is 24V, the power supply voltage can be 24V. _x000D_ Signal inputs with optical coupling isolation. To ensure that the capability of anti-interfence. _x000D_ For use with PLC supported NPN type. Must have a ground wire. _x000D_ For with encoder requires constant speed of the encoder continuously rotate more than 0.5 seconds. _x000D_ Frequency/ Voltage converter module, the response time is about 0.3-0.5 seconds. _x000D_ If the signal input is turbine flow and so on, an 817 optical coupler and a resistor were needed to match the flow meter normally because of the signal match. _x000D_ _x000D_ Corresponding relationship:_x000D_ When the F / V with the resistance transferred to an intermediate value, F / v corresponding to the following relationship, 100HZ = 0.1V, accuracy is 1%. It can not reach to 2 digits after the decimal point if relatively high precision of the occasion is not enough._x000D_ _x000D_ 0.1V = 100HZ_x000D_ 500HZ = 0.5V_x000D_ 1KHZ = 1V_x000D_ 2KHZ = 2V_x000D_ 3KHZ = 3V_x000D_ 4KHZ = 4V_x000D_ 5KHZ = 5V_x000D_ 6KHZ = 6V_x000D_ 7KHZ = 7V_x000D_ 8KHZ = 8V_x000D_ 9KHZ = 9V_x000D_ 10KHZ = 10V_x000D_ Each 0.1V DC of correspondence between the frequency 100HZ. When the correspondence if allowed, can be corrected to adjust to the board potentiometer._x000D_ _x000D_ Package List:_x000D_ 1 x Frequency to Voltage Converter
