PWM to Voltage Adjustable Converter Module 0%-100% to 0-10V _ICStation.com

PWM to Voltage Converter Module 0%-100% to 0-10V PWM Adjustable Converter Power Module for PLC MCU Digital to Analog Signal

Description:
1. The PWM transfer voltage module LC-LM358-PWM2V converts the PWM digital signals into 0 to 10V analog signals.
2. It can be used as signal interface switching for PLC or other industrial control boards. The output voltage is regulated by adjusting the duty ratio of the PWM.
   The modules are small in size and easy to use in different places.

Features:
1>. MCU embedded technology
2>. Easy to operate, fine tuned by potentiometer
3>. Select the PWM signal input level range through short-circuit
4>. The module is smaller, easy to carry and use

Parameter:
1>. Work Voltage:DC 12V-30V; (> 100MA)
2>. PWM Receiver Frequency:1KHZ-3KHZ
3>. PWM signal input level range:
    The peak of 4.5V to 10V level. The short cap install in ‘5V’. This level is used for normal controller or 5V MCU
    The peak of 12V to 24V level, so inserted in 24V. The short cap install in ‘24V’. This level is used for normal PLC controller
4>. Conversion range:0%-100% PWM to 0-10V
5>. Allowable error:5%

Hardware Interface:

VCC	DC 12V-30V
GND	Ground
PWM	Positive of PWM input signal
GND	Negative of input signal
VOUT	Output Voltage 0-10V
GND	Output Voltage Ground

Operation instructions:
After power on, without input signal, the output is 0V, so only input can output.

The first time when the power is on, it is best to do a calibration debugging: Input a 50% duty ratio signal to PWM/GND and adjust the relative amplitude short cap.

The frequency is 1KHZ-3KHZ, Measured VOUT and GND with a multimeter and it will display 5V.

Adjust potentiometer to make sure display 5.00V on multimeter. This will calibrate your pulse signal to this module.

When the frequency changes, the correspondences may be offset and need to be re calibrated.
The output voltage can be adjusted by adjusting the duty ratio.
The accuracy can be controlled by adjusting the potentiometer.

Hot Sale!!! STM32F4 Micropython Board from ICStation.com

Dearest Friends,

Much thanks for your order and join our website. Here we have this Hot Micropython Board recommendation to you. 

Click here to get: http://www.icstation.com/stm32f4-micropython-board-stm32f405rgt6-pyboard-stm32-micropython-core-development-board-module-flash-1924kb-sram-with-wire-p-11882.html

The #MicroPython #CoreBoard brings everything necessary for getting started in μPython with the #STM32. In addition, thanks +BitBastelei wonderful project about it. ^0^

Product Description:

• MicroPython is a lean and efficient implementation of the Python 3 programming language that includes a small subset of the Python standard library. And it is optimized to operate on microcontrollers and in constrained environments.

• The MicroPython pyboard is a compact electronic circuit board which operates MicroPython on the bare metal. It provides you a low-level Python operating system which can be used to control all kinds of electronic projects.

• MicroPython is packed full of advanced features such as an interactive prompt, arbitrary precision integers, closures, list comprehension, generators, exception handling and more. Also it's compact enough to fit and operate within just 256k of code space and 16k of RAM.

• MicroPython aims to be as compatible with normal Python as possible to allow you to transfer code with ease from the desktop to a microcontroller or embedded system.

• MicroPython is a full Python compiler and runtime that runs on the bare-metal. You get an interactive prompt (the REPL) to execute commands immediately, along with the ability to operate and import scripts from the built-in filesystem. The REPL has history, tab completion, auto-indent and paste mode for a wonderful user experience.

• MicroPython targets to be as compatible as possible with normal Python (known as CPython) so that if you know Python, you already know MicroPython. On the other hand, the more you learn about MicroPython, the better you become at Python.

• This pyboard is equipped with STM32F405RG microcontroller which built-in 168 MHz Cortex M4 CPU with 1Mb flash ROM and 192K RAM.8. In addition to implementing a selection of core Python libraries, MicroPython includes modules such as "machine" for accessing low-level hardware.
