8 Channel DPDT Relay

Low Cost 8 Relay DPDT Control 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 Eight Channel DPDT Configuration

The 8 Channel DPDT Relay includes four DPDT relays with your choice of 1, 3 or 5 amp DPDT relays and are also available in remote wireless configurations.
