Solid State Relay

[Copper Beech]

I am using Solid state relays to switch on 5.5k elements. I also want an indicator to light when the relay closes. The problem I have is that when the relay is open the LED glows, when the relay closes the LED just glows brighter. The only thing I can think of is that there is some sort of leakage across the relay in its normal open state. Anyone know why this is happening and is there a fix for this. TIA.

Use a 12volt indicator across the relay input.

Use a 12volt indicator across the relay input.

Yeah, I’ve done that before. Just really wanted to know that the relay was operating and there is an output to the elements.

I doubt if there is an easy way with the indicator you have.
The cause is probably that there will be a snubber capacitor across the triac in the SSrelay and that will pass sufficient current to bring on the led.
Probably a small incandescent, say 10 or 15 watt, would work, or you could experiment with a capacitor across the load; must be X rated for such use if you do.

Could replace the 240v LED indicator with a 240v neon, a neon shouldnt strike at anything less than about 70v
