The Raspberry Pi is a credit card-sized computer capable of running full-fledged Linux distributions such as Raspberry Pi OS, ...

I’d use the current running through the negative path to energize the relay, closing a switch that was completely independent of the RC receiver. The Arduino has a 5V output pin, so I made that ...

When it comes to isolating your microcontroller’s sensitive little pins from high voltages, ground loops, or general noise, nothing beats an optocoupler. And while simple on-off control of a ...

“By adding optocouplers and relays, you can use PLC, DCS, or remote I/O modules with 5-24V logic circuits to operate 120V AC/DC contactors.” The XTA-120V-6 six-channel optocoupler is intended for use ...

While the Arduino organisation has been making industrial single-board ... It is essentially DIN-rail module with relay outputs and sensor inputs – four 10A 250V (400Vmax) relays for load switching (4 ...
