2013年4月15日 · Because a SPDT relay is not more complicated than an SPST relay. A SPDT SSR has to be carefully designed to prevent both switches from being closed at the same time (in other contexts this is called cross conduction).

2008年9月9日 · Hello All, I have been trying to think of a way to make a Single-pole double-throw solid-state relay circuit out of some MOSFETs that I have laying around. I determied that I wanted to this SSR to be bidirectional so that it will behave as much like a …

2015年5月17日 · Need a SSR circuit to remotely control a well pump I want to use a christmas light remote controller to activate the "coil" (control) side of a NO SSR to power my irrigation well pump. It is a 1hp 208vac pump. Not easy to find an spdt SSR so I'm assuming I need to use two relays, one for each AC leg.

2013年4月15日 · Mais il me semble que les gens voudront toujours basculer entre deux signaux/rails d'alimentation de manière synchrone. Y a-t-il donc une raison pour laquelle les relais statiques SPDT sont si rares (dans le sens où sur Farnell il y a environ un millier de SSR SPST, mais 2 SSR SPDT dans un boîtier DIP ou SMD).

2023年10月1日 · When you are dealing with voltages higher than what your board operates at, relay contacts are a simple way of isolating that voltage. If you want a solid state solution you are often building a layer of isolation that that is a pain in the butt. A SSR is just quick, easy and replaceable when it fucks up.

2015年4月12日 · 3 way SSR? Hello I am setting up a three way switch but realized all SSRs have just the NO and COMM. Any way to add a NC?

2017年11月11日 · You would need a transistor not gate to invert one ssr when the other is switched on. But if you are switching the ssr with a spdt then you don't need any transistor.

2023年8月25日 · The controller appears to have 2 SPDT relays, you are just using one of them. Any heating circuit need some form of overtemperature protection. SSR's (or any relay) may fail closed, rendering the temperature controller useless; the …

2020年6月28日 · The problem I see him facing is that using a low-voltage relay to switch the mains line will probably require an extra power supply that has constant power for the relay. That greatly complicates things. If you want isolation, the simplest method would be to use the switch for only the mains voltage, and use a relay or SSR to switch the logic line.

2016年8月30日 · After some research I found that a potential solution would be to use a SPDT relay, which I do not have on hand right now. I do however have a spare SSR relay (SSR-25DD).
