    Solid State Relay Design For 24VAC

    Hi All I am new to the forum. I am working on a project, where i need to control 24VAC solenoids using my microcontroller. Previously i have used standard bulkier relays, but i now need some thing much smaller in design, therefore aim to use the AQH2213AX SSR. Can anyone advice, if the design...

    PID Controlled Peltier Heating and Cooling

    My goal is to rewire a Peltier AC unit by removing the on-board PSU and Analog temperature controller. I would like to convert the AC unit to Cool and Heat by reversing the Peltier modules polarity. Then control both heating and cooling functions with a PID. Then running it all with an external...

    DC SSR half cycle

    Hi everyone, short version: I've been struggling to find an optocoupler for my application. I think this one could work: Crydom DR06D03 but the datasheet lists the turn-on and turn-off times as "1/2 Cycle" and I don't get what it means since it's all DC on both input and output side. Crydom's...
