Why are you just focusing on thermal management as the sole issue. What sort of isolation do you require. E.g. why not switch to digital isolation. As such, I'm not sure how I can share any solutions but if I read between the lines it does sound like you want to sell something. Is this all about CTR's...https://community.element14.com/members-area/f/forum/57153/how-do-you-find-what-you-re-looking-for-on-the-element14-community/237731Thu, 06 Aug 2026 12:47:00 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:366de0be-e4b4-4f37-9e4f-54ee4ba0cb94beacon_daveI mainly use the advanced search but often have to tweak the URL query manually to narrow down the results. Knowing the serpauthor value for a user here helps enormously, as the drop down combo box allows you only to pick from the top 12 or so users and often the one you want, doesn't appear in the list to pick from, so you have to do it manually in the URL. That said, there is some content that is very hard to find even when you know who wrote it and you know that it is definitely in there somewhere. I often encounter this when I want to reference existing related content in a forum comment.https://community.element14.com/members-area/f/forum/57156/question-industrial-optocouplers-keep-failing-on-site-what-thermal-management-products-can-solve-this-issue/237730Thu, 06 Aug 2026 09:03:00 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:ea4a2a2b-37e5-4a84-95f4-f760d4ef998fgeraldsLEDs have a limited lifespan. Are other types of coupling elements suitable for your industrial application instead of optocouplers? If so, try replacing them, ideally with a 1:1 pin-compatible interface. ...Well, only optocouplers allow for static coupling, e.g., direct on/off; the others are dynamic couplers, capacitive/inductive, or especially wireless, which makes things complex and expensive. So, choose a sensible approach. Cooling also adds to the cost.https://community.element14.com/members-area/f/forum/57153/how-do-you-find-what-you-re-looking-for-on-the-element14-community/237729Thu, 06 Aug 2026 08:47:00 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:79b0e5cd-2719-427f-8843-b1401b74a8c7Andrew JI typically use the search box with varying results. Next time, I’ll keep track of how it panned out and comment. As for travelling I couldn’t vote with those options. During my career I’ve lived and worked in Republic Of Ireland, France, Spain, Germany, Italy, Turkey and of course, mostly, the UK. I feel I’m forgetting somewhere! I don’t live abroad though and never felt the desire to really, so not a nomad. Travel on holiday a fair bit and visited numerous countries.https://community.element14.com/members-area/f/forum/57139/hello/237728Thu, 06 Aug 2026 08:29:00 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:77caad8f-0e3b-48b1-bbcb-0d54039a6537Em0keThank youhttps://community.element14.com/members-area/f/forum/57156/question-industrial-optocouplers-keep-failing-on-site-what-thermal-management-products-can-solve-this-issue/237727Thu, 06 Aug 2026 08:23:00 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:45db0fb1-f681-48c5-ab10-b82a85e7fc90michaelkellettNot enough information here to offer any advice.

Besides standard cooling fans, I’m wondering what mature thermal management products, thermal conductive components or circuit design solutions are available to reduce high-temperature damage. It would be much appreciated if anyone could share solutions that have been applied in industrial or automotive projects.automotive electronicsthermal managementoptocouplerindustrial automationhttps://community.element14.com/members-area/w/polls/28096/question-of-the-monthWed, 05 Aug 2026 20:35:00 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:4573ba84-a032-4f65-87d6-19bf21df320dcstantonComment in the forumpollQOMquestion of the monthsurveyhttps://community.element14.com/members-area/f/forum/57153/how-do-you-find-what-you-re-looking-for-on-the-element14-communityWed, 05 Aug 2026 20:34:00 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:d5e49df2-dddd-4665-b629-e9ff88858555cstantonOnce upon a time, using Google was frankly the easiest way to find what you wanted on the Community, but since we changed platforms, I'm wondering how much you may use the search box at the top?

I think the Synthstrom Audible Deluge was one of the few that offered near unlimited steps and was restricted by installed RAM rather than by the user interface design. In the end I opted for a sequencer that could chain sequences together to give the equivalent of 2048steps which was more within my ball-park, however it is a fiddly user interface to edit in 'old school' blocks of 16 steps arranged in 8 pages and then chained into 16 groups. A scrollable 'piano roll' type user interface perhaps has advantages in some use cases.https://community.element14.com/members-area/f/forum/57067/who-s-in-the-uk-and-has-caved-in-and-bought-air-conditioning/237721Wed, 05 Aug 2026 17:11:00 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:fabbb7ce-d199-4737-b497-80c7b823d235kmikemooAt work, my window cracked due to the heat (dark colored shade).

I think more than anything, a big subset of them prefer simplicity, hence cloud is probably attractive, because it is one less thing to manage, carry, keep safe, upgrade, charge, and so on.
