Specification: Condition: 100% Brand New Item Type: Voltage Converter Material: Plastic + Metal Color: As Shown in the Picture Weight: Approx. 44g Optional Type: K3.3P-5V, K3.3P-10V K3.3P-5V: Input 0-100% PWM signal of 3.3V electrical level, output 0-5V K3.3P-10V: Input 0-100% PWM signal of 3.3V electrical level, output 0-10V Parameter: 1. PWM Signal Receiving Frequency Range: 100Hz-3KHz. 1KHz-3KHz is recommended. PWM signals of other frequencies can also be customized. 2. PWM Signal Input Electrical Level Range: When peak-to-peak value is 4.5V to 10V, the input signal is selected to be 5V electrical level model. This type of electrical level signal is mainly for the conventional industrial control card (such as MACH3 board), 5V CPU interface. When peak-to-peak value is 12V to 24V, the input signal is selected to be 24V electrical level model. This type of level signal is mainly for the conventional PLC interface. 3. Analog voltage output parameters, following is output 0-10V to illustrate. After power-on, when there is no input signal, the output is 0V, and there is output when there is input. The conversion correspondence is generally set at the factory. For the first power-up, a calibration can be done: find a 50% duty cycle signal to DIN-, DIN+, the amplitude corresponds to the selected model, 3.3V or 5V or 24V. The frequency is 1KHZ-3KHZ. Use a multimeter to measure two ports of AO and GND. At this time, the table is displayed at 5.4V. Adjust the potentiometer on the board so that the multimeter is displayed at 5.40V. This calibrates your pulse signal and the correspondence of this module. The resolution of this module is 0.1V. The output current capability is 10mA. If percentage of the duty cycle is inverse to the voltage, you can check (or cross-check) the pin that sets the PWM output in MACH3 software. STEP LOW, ACTIVE is the check box for the foot. 4. The input power supply has a voltage range of 12-30VDC (power supply requirement: more than 100mA). It is recommended that the power supply voltage be 15-24VDC. At 12V electrical level, the power supply cannot be powered by 12VDC, it should be powered at least by 15VDC. Ports: 1. DIN+: PWM signal is input positive. (for common cathode connection, it connects to PWM signal, for common anode connection, it connects to 5V or 24V of the signal terminal) 2. DIN-: PWM signal input is negative. (for common cathode connection, it connects to GND of the signal terminal, for common anode connection, it connects to PWM signal) 3. 12-30V: Power input positive terminal. 4. GND: Power ground. 5. GND: Signal ground. It is connected to the power ground GND port. 6, AO: Analog voltage (0-10V or 0-5V) output port.
