Rated at 30A, the series 300XBX is a high-power relay used in power transfer circuits in PC servers, power supplies, test equipment and in other high capacitance/high ...

When voltage is applied to the coil then the relay switches and now T1 (plus ... In this second application we can use the DPDT switch to choose between 2 different load and have a visual indication ...

Using custom PCBs hosting banks of DPDT relays, he progresses from the basic AND and XOR gates to half adders and full adders, explaining how carry in and carry out works. Everything is modular ...
