Description:

• PWM digital signals into analog signals from 0 to 10V.
• Convert PWM digital signal into 0 to 10 v analog signals.
• Power Input Range: 12V-30V (Power requirements: more than 100MA)
• Signal interface switch can be used for PLC or other industrial control board.
• PWM Reception frequency range: 1 KHZ - 3 KHZ.
• Current output capacity: 10MA.
• Resolution: 0.1V.
• Usage: by adjusting the potentiometer board, can match the calibration of PWM signals of different frequency pulse

PWM signal input level range:

• 4.5V to 10V peak to peak level,  jumper inserted at 5V. This type signal mainly for conventional industrial control card (such as MACH3 board), for 5V the CPU interface. 
• 12 to 24V peak to peak level, jumper inserted at 24V. This type signal mainly for conventional PLC interface

Note:

When the signal input port is not connected, the output port gives 10V.  The first time when we power on this module, we better calibrate it: find a 50% duty ratio signal, 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 5V. We adjust the potentiometer on the converter module to make multi-meter shows 5V sharp. After this is done, we have calibrated and matched pulse signal 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 or un-select PWM output pin STEP LOW / ACTIVE in MACH3 software
