Witryna24 sie 2016 · A single pole single throw switch and a 12 volt automotive relay seems obvious. If your "signals" are using tiny currents, like a milliamp or so, you might need gold plated contacts. They are sometimes called, "dry" contacts. Automotive relays aren't built like that. They are designed for massive current like 10 amps. Witryna3 gru 2024 · Bistable relays retain their switched position even if supply current to the coil fails. This means bistable relays can prevent the loss of information on the current switching status. In addition, with a bistable relay, the vehicle’s computer grounds the circuit to engage the relay. Once the coil is not energized, the relay is still doing ...

WitrynaThese logical states can be presented using electromechanical contacts in the form of switches or relays as a logic circuit element. The implementation of switching functions in digital logic circuits is nothing new, but it can give us a better understanding of how a single digital logic gate works. Witryna24 lip 2024 · The relay itself isolates the control signal terminal (operating voltage) and switch terminals (NO/NC) electrically. Or you can avoid a transistor array by using solid state relays (SSR). They have a wide operating voltage, longer life, no mechanical noise and they are optocoupled too. You can directly drive SSR from microcontrollers.
