Dual DPDT Relay
2 Channel DPDT Relay Board

Double Pole Double Throw Relay
A DPDT 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 switch.  A DPDT relay board is most commonly used for signal switching applications, but can be found in high power switching applications as well.

Low Cost Dual DPDT Configuration
The R2xDPDT includes two DPDT relays with your choice of 1, 3 or 5 amp DPDT relays. Features include no-click startup, 2 LED status lights, and E3C compliance.  Relays can be controlled at 9600 baud and is compatible with ANY computer or microcontroller capable of delivering RS-232 data.  Even a no-frills design deserves a high-quality driver stage, and that's exactly what we put on the R2x controllers.  Fast-reacting flyback diodes help shunt dangerous voltages away from the driver circuit.  For more detailed information and to order, please click on the links below.

Latest Advancements
Look for our ProXR series controllers for the latest advancements in signal switching!  The
ProXR series is capable of controlling up to 256 relays.  Control one relay at a time or all 256 relays at once with manual and automatic refreshing command set!  With our DPDT signal switching, the ProXR Series are built from the ground up with Expansion in mind.  Simply Chain the XR Expansion Modules, one after another, to meet your computer controlled switching requirements.  Your system will grow as your needs grow by simply plugging in modules as needed.  All boards in the ProXR Series will have the ProXR suffix in the part number.    For more detailed information and to order, please click on the links below.
