24volt SSR- microcontroller connection

[crutschow]

That is the basic lay out i used. the i had the resistor connected to the base, and the 5 volt supply connected to the resistor, the ground from the relay and the supply shared the emiitter, and the 24 v control line to the collector.

i used a 5volt power supply to sub for the microcontroller at the moment, i just used a momentary switch in line with the base

The circuit looks correct. If everything is properly connected, touching any of the leads should have no effect. Sounds like a bad connection somewhere.

ok so i will double check all the connections make sure there all solid, i ordered a bunch of new transistors off ebay, possible mine got mixed up in storage. so ill give this a shot when the new transistors arrive ( i got the 2n3904 NPN transistors)

i guess ill do some work on my darlinton LED drivers untill those arrive.

thanks
