Using method:
PWM input frequency range: 1KHZ-3KHZ
PWM input level range:
4.5V to 10V peak to peak level, jumper inserted at 5V. This type mainly for conventional industrial control card (such as for MACH3 board), for 5V the CPU interface.
12 to 24V peak to peak level, jumper inserted at 24V. This type mainly for conventional PLC interface

0-10V analog voltage output explanation:
When the input port is not connected, the output port gives 0V. The first time when we power on this module, we better calibrate it: find a 50% duty ratio , connect to DIN-, DIN+, the amplitude matches corresponding jumper. When frequency is at 1kHz ~ 3kHz, use a multi-meter to test AO, GND. The meter should be showing around 5.4V. We adjust the potentiometer on the converter module to make multi-meter shows about 5.4V. After this is done, we have calibrated and matched pulse with this converter module. The module has a definition of 0.1V. Output current 10mA. If duty ratio is in opposite to voltage, we can select PWM output pin STEP LOW / ACTIVE for MACH3 software.

Package Included:
1 x PWM to Voltage Converter

Note:
After power-up, when there is no input , the output is 0V. There is output only when there is input.
