I burned out a solenoid on my apprenticeship test. Turns out it was a 24v coil, I thought it was a 230v so I had wired it up to mains. Smoked it while the tutor was watching. That’s how I remember to always check coil voltage 😂
great explanation of solenoids. i was told when i was learning there just relays that control liquids and gasses you can get million of different combinations normally closed normally open 2 way and 3 way differnent control voltages just to name a few. also when the coils go wrong short out and melt they are right pigs to get off without bending the shaft.
I found a Magnet Stick handy for testing solenoids too, around £30 from RS. We also have illuminated solenoid caps on some of our machinery to aid fault finding
Played with many of solenoids in ammonia chillers, you just explained how they work better in 9 mins than what our tradesman's could in 12-24 months.
Glad it helped ,
Nailed it mate, 👍

If I had had a pound for every time I had mixed up 240 and 24 v components or found it on jobs I would have enough to buy a big old bag of cocaine

Good real life demo and explanation. Cant think of anything else to add. All the best. Cheers
Glad you enjoyed it

DC ones always need a back emf diode across them to stop them burning relay contacts or plc outputs.
