Features PWM converts digital signals into an analog signal (0 to 10 V). PWM signal input frequency range: 1 KHZ-3 KHZ. The digital input signal can be a 5V or 24V level 0-100% PWM signal. The analog output signal can have a voltage of 0-10 V. This module is easy to connect and easy to use. Can be used for industrial control panel PLCs or other signal interface circuits. PWM signal input level range: 4.5V to 10V peak-peak level, jumper placed at 5V. This type of signal is mainly intended for conventional industrial control boards (such as for MACH3 cards), for 5V the CPU interface. 12 to 24V peak-peak level, jumper placed at 24V. This type of signal is mainly intended for conventional PLC interface. Specification: Condition: 100% brand new and high quality Current: Max. 12mA Input voltage supply: 12-30V Size: Approx. 5 x 4.5 cm / 1.97 x 1.77 inch Weight: 20 grams Quantity: 1 pc 0-10V analog voltage output explanation: When the signal input port is not connected, the output port gives 0V. The first time we turn on this module, we can better calibrate it: find a signal with a working ratio of 50%, connect to DIN, DIN+, the amplitude corresponds to the corresponding jumper. When the frequency is 1 kHz ~ 3 kHz, use a multimeter to test AO, GND. The meter should indicate about 5.4V. We adjust the potentiometer on the converter module so that the multimeter indicates about 5.4 V. After this is done, we calibrated and tuned the pulse signal with this converter module. The module has a definition of 0.1V. Output current 10mA. If the duty ratio is opposite to the voltage, we can select PWM output pin STEP LOW/ACTIVE for MACH3 software. Package included: 1 x PWM Signal to Voltage Converter Note: After switching on, if there is no input signal, the output is 0V. There is output only if there is input. Package List
