I recommend folks use mosfet relays labeled for bed heaters on amazon - the ones in the wiring image (as well as may others online listed as mosfet switches) use the f5305s P-channel mosfet, which isn't really meant to handle more than 20v maximum. I had ordered the ones in the image and both burned out on me within an hour of use, both failing high. This is obviously a huge safety issue, especially if it were hooked up to a chamber heater. I used a mosfet meant for bed heaters and its been working great.
@BigBeau I also had a hard time finding mosfets rated for a 24v signal input. Did you need to change any of the wiring to use the heated bed mosfet instead? Also most of the heated bed mosfets look rather bulky, did it cause any trouble fitting it in nicely?
@WillStrain_1967462 the only modification I made was removing the mosfet heatsink. it's not even switching an amp so its pretty much unnecessary. I did have to trim some of the plastic off the underside of my k1c to vhb tape it but I could have just made a mount or chosen a smaller board instead (like the DiGiYes one on amazon)
Wiring didn't have to be changed, it's the same as in the included guide

@BigBeau Interesting. I have been using mine for a couple months without any issues so far. Can you DM me a link to the one your ordered? (edited)
