A simple and convenient way to interface 2 relays for switching application in your project. This relay driver boosts the input impedance with a regular BC547 NPN transistor (or equivalent). Very ...
Relays usually are driven using optocouplers, which offer isolation between analog and digital grounds to ensure that switching currents in the relay coils do not affect the noise margin of the ...
Computer Controlled, relay board designed to be either operated manually via switches on the board or nine way Type Connector via PC or laptop. Computer Controlled, relay board designed to be either ...
