Problem with nonresponsive relay
Problem with nonresponsive relay
(OP)
Hey everyone...I'm new here and was hoping yall could help me out with a proble...
I've got a temperature controller which controls an SSR via an 8v output. The SSR is then connected (through a switch) to a valve. My problem is that the SSr will open the valve, but it doesn't seem able to stop when the temperature control lets off...I think it could be an interaction of the valve/SSR b/c if I simply flip the switch off-on quickly after the temperture control quits then the valve does stop...I hope tht makes sense and ANY help would be greatly appreciated...Thanks

RE: Problem with nonresponsive relay
If you cannot remove the snubber, try and connect a lamp (correct voltage, power a few tens of W) parallel to the coil. If it drops out then, it is snubbers or some other capacitance (cables, perhaps).

WHERE did you put it?
The lamp (or snubber) shall be parallel to the load (coil).
And, please, please, do not use a tantalum capacitor! They are polarized. Can't take AC. Also, what voltage is that capacitor for?
I think it is time that you get professional help with that.

Just add an additional load to the output of the SSR. A small light bulb is fine such as a 25 watt or greater.
