A DPDT Relay, Double Pole Double Throw Relay, has a single coil with two arms that move at the same time. There are two completely separate SPDT switch mechanisms inside a DPDT relay. A DPDT relay board is most commonly used for signal switching applications, but can be found in high power switching applications as well.
RS232 DPDT Relay Board
RS232 Relay or Serial Relay Controller allows computer controlled switching using the Serial port of your computer. Select RS232 relays support 8-Channels of 8-Bit / 10-Bit
Analog to Digital Conversion (A/D), and include an XR Relay Expansion Port for adding additional relays to the RS232 Relay Controller Board (look for PROXR in the part number).
Supports any COM Port
An RS232 Relay supports any available COM port at any standard baud rate, allowing easy integration into any program that support serial communications. The RS232 Relay is ideally suited for applications that require data collection and control from a single device. Built-in temperature sensor allows temperature monitoring, analog to digital conversion, and relay control from a single device. RS-232 Interface Supports baud rates up to 115.2K Baud.
Setup for the R45DPDT RS232 relay shown above using the optional QS12 Quick Start Kit. Simply Connect the Serial Interface to your Relay Controller, connect the Power and Serial Cable and start sending commands.
Summary of RS232 DPDT Communications

Supports 2-way communications
Quick Start Kit available for easy PC connection
Optional USB to RS232 Adapter allows easy connection to your computer's USB port
ProXR versions expandable to control up to 256 Relays using the XR Expansion Port
Control one relay or all 256 at once with manual or automatic refreshing command set
1, 3, and 5 amp versions available
No special software needed
All RS232 DPDT Controllers are SignalSwitch Compatible
Our RS232 DPDT boards offer your choice of 1, 3, or 5 amp relays and are available in many channel versions. Selected RS232 DPDT Relays feature the
ProXR Command Set and an
XR Expansion Port, simply look for PROXR in the part number. The XR Expansion Port will allow you to expand any ProXR model board to 256 relays using our
XR Expansion Modules.
RS232 - The Foundation for all Communication Technologies
While RS-232 is not built into some of today's motherboards, there are many applications where RS-232 is still the best choice. Using a simple USB to Serial Adapter allows you to use RS-232 devices with ease. 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. RS-232 devices are perhaps versatile and most popular choices because of their ability to adapt to any other communication protocol. For instance, using 3rd party devices, RS-232 relay controllers can be controlled from GSM modems, Ethernet to Serial Adapters, WiFi to Serial Adapters, USB to Serial Adapters, Bluetooth to Serial Adapters, and Wireless Mesh Network to Serial Adapters. RS-232 will continue to adapt to all emerging technologies, as the foundation for all communication technologies has provisions for RS-232 communications.
Easy Connection with the Quick Start Kit
The video above shows how easy it is to connect an RS232 Relay to the computer with the optional Quick Start Kit. The
R45Pro 4 Channel Relay Controller is shown connected to the optional
QS12 Quick Start Kit. Quick Start Kits provide everything you need to begin using your RS232 Relay Controller. Kit includes a high quality regulated switcher supply, serial cable, and RSIO adapter.

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.
