I have a relay contact rated at 220v dc which is supplied
with a 24vdc from the panel,for it to trip the
dampers(24vdc).What if the application of the relay changes
so that it should work at its rated 220vdc then will it work
at 24vdc supply given or any other consideration needs to be
taken .....
Answer / Ajay Kumar Kanaujiya
A relay contact rated for 220V DC will not work with a 24V DC supply because the voltage is too low. To use it with 220V DC, you would need to connect a power source that provides 220V DC. If the application of the relay changes and it needs to work at its rated voltage, then ensure that the new power source can safely provide the required voltage.
