2-Channel SEQUENTIAL Relay Timer Module, 1-180 second (CI027).Please check the individual product page for maximum relay voltage and current ratings and additional timer boards required to repeat the cycle. Here are some boards that can be used for this set-up. You simply wire the relays as shown in the diagram below (click for larger image in new tab). If you want a motor to automatically switch direction every few seconds to every few hours, we have a few relay boards that will do this for you. Automatic Timed DC Voltage / Motor Reversing Switch Note: Please bear in mind the higher current drawn if the motor is reversed without first being stopped and ensure that it does not exceed the rating quoted for the board. The DC motor will move in one direction when only Relay-1 is ON and in the other direction when only Relay-2 is ON. The motor will be at rest when both relays are OFF or both relays are ON. ![]() The approach these solutions use to reverse the polarity of a DC supply voltage employs two SPDT relays that are wired as shown below (click for larger image in new tab). Here you will find some solutions to your needs. From manual push button control to automatic and RF remote control. We have a range of boards that allow you to do this automatically or manually. If you need to reverse the direction of a DC motor or the polarity of a DC voltage we have solutions. DC Motor Reversing Circuits: Timer or Remote Control
