I’ve been playing with one of these… https://www.sparkfun.com/products/16833
Works really well. One question, even when a relay is off, it leaks a small amount of current. From what I understand this is normal. It does however cause the LEDs in the (240v) device I’m controlling to flicker even when the relay is off. Is there a good way to filter out this interference?
You could toss in a https://en.wikipedia.org/wiki/Bleeder_resistor - these are normal resistors, wired in parallel to divide the voltage
I am afraid the bleeder will not help guys. That is to discharge a capacitor faster in case there is voltage left after power-off.
A TRIAC (as used in solid relays) will always produce a leak current. The datasheet is showing 4 to 6 mA depending on the solid-state relay used and that has that could be enough to trigger LED’s. The only way to reduce (BUT not eliminate) is the design. e.g. Look at https://components101.com/triacs/leakag … inimize-it . Maybe in this case it is better to have a mechanical relay.
Thank you for the info paulvha! I’m still learning the ropes!
Could you use a second relay to toggle power to the first? The leakage current might not be enough to activate the second relay.
