Specification: Item Type: Transmitter ModuleMaterial: PCB Power Supply Voltage: 9V ~ 24V Signal Input Voltage Range: 4～24V Signal Input Frequency Range: 5Hz～500Hz Signal Input Duty Ratio Range: 0～100% Output Voltage: 0.00V ～ 5.00V/0.00V ～ 10.00V Input Method: J1 Pad On The Circuit Board: The default is open circuit, which has not been used yet. Output Mode: J2 Pad On The Circuit Board: Open circuit (output 0.00V ~ 5.00V); short circuit (output 0.00V ~ 10.00V), the default is open circuit. Application Scope: Remote data acquisition and control equipment; Module Interface: 24V: Power supply positive port (9V ~ 24V) G: Power ground interface IN: Signal input positive interface G: Signal input negative port OUT: Signal output interface (0.00V ～ 5.00V/0.00V ～ 10.00V) G: Power ground interface Output (0.00V ～ 5.00V) Resolution: 0.050V/D (Volt/Duty Cycle) Output (0.00V ～ 10.00V) Resolution: 0.100V/D (Volt/Duty Cycle) Calculate The Measured Duty Cycle Method: (output voltage (V)/resolution) = duty cycle (%) For Example: Output (0.00V ~ 5.00V) output is 2.5V (2.5(V)/0.05) = 50(%). Package List: 1 x PWM to Voltage Module Note: When the output is 0.00V to 10.00V, the power supply voltage must be 15V.
