[QUOTE="ArloG, post: 1164887, member: 418555"] It should work fine. Personally, chinesium aliexpress electronic components give me the heebie-jeebies. I could not even find a datasheet for the one you have right now. I bought an assortment of 78XX, LM series voltage regulators with ST Micro logos. Every single one a fake. And when approaching half the rated current of the originals. Puked all over the place. Never ever again. Why take a chance? The link I gave for the Opto brand. They are excellent. So are Crydom's. There are many SSR's of different name brands with the same form factor. Such as the first one. A Crydom (and others) clone. My concerns using datasheets would be switching time. Quite important in my shoes where my encoder chops every actuator screw rotation into 20 slices. Too much lag turning on or too much 'hang-time' when turning off. Yeahhh.... Anyhow. The photo shows the one I use. I have boards and boards with them (so you don't think I was full of b.s). And every one has operated probably millions of cycles at the very least. And each one would last years and years more. You're free to look up the data sheet for them. I would say that in operation they probably switched every 0.05 seconds. At times continuous. And they were triggered with u-shaped photo switches, but on a more grand scale than ours. Anyway. Only suggestions. Not meant as criticism (which I handle pretty well....because my stuff works). I did not really see where your encoder wheel is mounted or how fast it spins. A hint to probably shorten the switching time would be to measure the voltage at the input terminals and fashion a series resistor to lower the switch-on voltage to a touch above the SSR threshold. But you should be just fine if the encoder turns slow. [/QUOTE]
