Compact and portable, it features an embedded MCU for stable performance and a fine-tuning potentiometer for easy calibration, making it ideal for industrial control systems, PLCs, and CNC interfaces. ## Description DollaTek trademark Reg.NO:013726393PWM turn voltage module LM358-PWM2V can convert PWM digital signal into 0 to 10V analog signals.Can be used in the PLC or other industrial panel switch signal interface.By adjusting the PWM duty ratios to adjust output voltage.Module size is small, easy to apply in different places. Module working voltage: DC 12 v - 30 v.(power requirement: more than 100 mA)PWM signal receiving frequency range: 1 KHZ - 3 KHZ;PWM signal input level range:Fengfeng value of 4.5 V to 10 V level, jump needle at 5 V.The class level signal mainly for conventional industrial control CARDS (e.g., MACH3 boards), 5V CPU interface;Fengfeng value between 12 and 24 v level, jump needle at 24 v.The class level signal mainly for conventional PLC interface.PWM conversion range: 0% - 100% PWM conversion 0 to 10V Permissible error: 5%. VCC: work power 12 v - 30 v.GND: working power。PWM: input PWM signal positive pole.GND: the input signal is negative end.VOUT: 0 to 10 v output voltage.GND: output voltage.Instructions: after power on, there is no input signal, the output is 0 v.Electricity for the first time, it's best to do a calibration debugging: find a 50% duty cycle of the access to the PWM signal, GND, corresponding to the relative amplitude jump needle.Frequency in the 1 KHZ - 3 KHZ, VOUT is measured with a multimeter, GND two ports, the table displays at around 5 v, adjust the potentiometer on the board, make says in 5.00 v on the multimeter. The calibration is your pulse signal and the corresponding relation of the module.When the frequency changes, there may be offset, the corresponding relationship needs to be calibrated.Output voltage can be adjusted by adjusting the duty ratios.Package Includes:1x DollaTek PWM turn voltage module 0%-100%PWM turn to 0v-10V voltage Review: Not fully isolated - Not truly isolated. The input and output grounds are connected together. Review: Sort of works - Ok, this does work but not well, well enough for my needs though. This module does power up and work on 6v but obviously you'll then only be able to use the 0v-5v output setting. On that note on the module I received, using a 24v power supply, with the PWM at 100% duty I could only get 3.9v on the 0v-5v setting and 7.6v on the 0v-10v setting. This means that you won't be able to get full RPM from your motor, mine was down by about 20% so I have used the 0v-10v setting to supply the 0v-5v input on my motor driver trimming down the output voltage to as low as it would go (around 6v). As I said it works for my application. I did try a 30v supply but it made no difference. ## Features - Easy to operate, can pass to fine-tuning potentiometer. - Through the short circuit choose PWM signal input level range. - Module is small, portable and easy to use. - MCU embedded technology. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07DK51KXR | | Best Sellers Rank | 73,415 in Business, Industry & Science ( See Top 100 in Business, Industry & Science ) 4 in Digital Signal Processors | | Guaranteed software updates until | unknown | | Manufacturer | DollaTek | | Package Dimensions | 15.5 x 9.8 x 1.5 cm; 10 g | ## Images ![DollaTek PWM turn voltage module 0%-100% PWM turn to 0V-10V voltage - Image 1](https://m.media-amazon.com/images/I/61gr8FRAgHL.jpg) ## Questions & Answers **Q: Can this be used with a 3.3v pwm signal like the output from a raspberry pi?** A: I have recently checked these modules and they do work with 3.3V logic providing that the PWM pulse width is adequately long to trigger the opto-coupler. I had three of 8 ordered come with with short circuit voltage regulators though. ( I removed the reg and supplied at 12.00V DC instead and they worked OK. The circuit is not very linear when used with pulse widths as intended ( ie to match the two stage low pass filter before the op amp ) due partly to the excessive capacitance (C5) connected across the opto coupler ( C5) input and also the op-to coupler response. It works better with this IC removed ( easy to do as its a PTH IC) but to get less than 1 bit error at 8 bit conversion major mods are required to the circuit including removal of the opto-coupler and a 2:1 gain increase in the op amp stage to give a nominal 0-5.3V output for 3.3V logic pulses When modified it can achieve better than 0.5 lsb linearity at 8 bit with an analogue output update rate of approx 50Hz. Stability and drift will depend on the stability of the 3.3V pulse train but if thats stable it can provide a cost effective and accurate DAC. ## Customer Reviews ### ⭐⭐⭐⭐ Not fully isolated *by A***R on 3 March 2025* Not truly isolated.
