MaiTech PWM Turn 0~10V Digital to Analog Module - Green
Function and role: PWM converts digital signals into analog signals 0 to 10V £¬ can be used for other industrial control panel or PLC signal interface switching. Use: PWM signal receiving frequency range: 1KHz~3KHz. PWM signal input level range: 4.5V to 10V peak level jumper inserted at 5V . This class level signal mainly for conventional industrial control card ( such as MACH3 board )£¬ 5V for CPU interface. 12 to 24V peak level jumper inserted at 24V. This class level signal mainly for conventional PLC interface. 0-10V analog output parameters: When no signal input terminal£¬ an output port is the first time the 10V power£¬ it is best to do a calibration debug: looking for a 50% duty cycle signal access to the DIN-£¬ DIN + £¬ the relative magnitude of the corresponding jumper . Frequency 1KHz~3KHz£¬ measured with a multimeter AO£¬ GND two ports£¬ then table shows around 5V£¬ adjust the potentiometer board £¬ the display on the meter at 5.00V . Thus calibrate your pulse signal and the module correspondence. Resolution of this module in 0.1V£¬ the output current capability 10mA£¬ if the duty cycle relationship of the percentage of the number of opposite voltage £¬ can be exchanged SIN-£¬ SIN + junction of the two input pin under test £¬ or to set the software MACH3 PWM output pin is checked ( or fork -election ) about STEP LOW£¬ ACTIVE foot corresponding checkbox . Power Input Range: 12V~30V. Power requirements: more than 100mA. Fixed: 4 M3 screw holes. Silkscreen underside module mark£¬ according to identify the connection cable. Identifies the following meanings: DIN +: PWM signal input positive terminal. (Common cathode connection time here then PWM signal£¬ common anode connection£¬ here then signal the end of 5V or 24V) DIN-: PWM signal input negative terminal. (Common cathode connection time here then signal the end of GND£¬ when common anode connection£¬ here to pick PWM signal) 12-30V: Power input positive terminal. GND: Power Ground. AO: analog 0-10V output ports. GND: Signal ground. Ground GND and power ports are interlinked. Other features: 1. Anti-reverse power supply capacity. 2. After power has a power indicator light. 3. By adjusting potentiometer board£¬ can match different calibration frequency PWM signal pulses.
