There are some computer control applications that are a little more demanding than simple on/off control signals. If you have an application where you need to safely control the speed of DC motors or the brightness of lights in a room, then our PWM series controllers may be exactly what you are looking for.
Summary of PWM 8-Channel Devices
Low-Cost 8-Channel FET Configuration
1200/2400/9600/19.2K Baud Operation
Control 256 Levels for Each FET
Programmable Power-Up Level
Programmable Power-up Memory
Two-Way Communication Capabilities
Quick Connect Terminal Blocks
2 RS-232 Input Levels
The PWM81 is perfectly suited for automotive lighting applications (except headlights), such as custom turn signals and interior lighting. The PWM83 is suitable for larger lights and small DC motors. The PWM85 is suitable for larger DC motors found in most robotic control applications.
8 Channel Light Dimmer Speed Controller
The PWM8x series controllers are built around a custom pulse width modulation processor. This new processor is dedicated to providing 256 levels of pulse width modulation for 8 individual channels. Coupled with powerful fets, the PWM8x is capable of controlling 256 levels of brightness for 8 individual light bulbs under computer control. Rated for use with resistive and inductive loads, the PWM8x is also a very suitable solution for DC motor speed control applications.
Easy USB Connection
The PWM8x series controllers offer as an option the
QS12 Quick Start Kit. The Quick Start Kit comes complete with a Power Supply, Serial Cable and RSIO Interface Board for easy RS-232 connection. For easy USB connections simply purchase the
USB to Serial Adapter and plug the serial cable to this adapter. This combination is actually better than using a device with a onboard USB port, because it eliminates most of your EMI problems while maintaining compatibility with today's computers.

By downloading the NCD Component Library you will receive over 40 samples from A/D Conversion to Duration and Pulse Timing and best of all it's FREE!! We want the user to be able to experiment with all the different samples available so as of right now the samples cannot be downloaded individually.
We've "Started" the Programming for You
With the NCD Component Library we've "started" the programming for you. We say started because these are fully functioning samples but we've also included the source code so you can customize them to your exact needs. Start by downloading the NCDComponentSetup.zip file from the NCD Component page.
PWM Sample
A fully functioning PWM Sample is included with the NCD Component Library. This sample demonstrates the PWM Command Set, Allowing you to Set and Store PWM Values. Compatible with all PWM 8-Channel Devices on this page. The sample can be run in Visual Studio and is fully customizable to your needs. Visit our
Component Library page and look for the PWMSample1.exe for a screen shot of this sample. Order your board and download the FREE NCD Component Library and you will be communicating with any NCD device faster that ever!
