I have a sugar cube relay which I am using with my controller. It turns On/Off when high or low signals are sent from the microcontroller. It can take upto 240V AC at 10 amps. The way the relay circuit board is that I connect the positive and negative of DC or AC Line and neutral at the input terminals, I get the positive and negative DC at the output terminal blocks or line and neutral at the output terminal blocks When I connected 120V AC Line and neutral wires at the input terminals of the relay, at the output I am only getting 12V AC. What could possibly the reason for this ? Is the relay broken ? It was working fine a few days ago. HkqVtk8a.jpg

Probably.

Does the AC load have a startup surge current or inductive motor?
THen you need to derate the contacts significantly or add an ICL inrush current limiter..
Read OMRON datasheets for advice.

Ya, by mistake I had connected a load directly to the relay. The high current must have damaged it. Because the relay can take around 5 amps. But even the relay shouldn't click. It does click and the output is getting reduced to 12 volts from 120 volts which is weird. It is behaving like a regulator.
