4 20ma signal generator 0 10v mv thermocouple current meter calibration signal source lb02 купить по лучшей цене

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.
