Question about piface digital 2

acca 11 hours ago

Hello

I have a piface digital 2, i'd like to know the max rated voltage for the relays

It is written 250VAC 10A on the relays body but 20V 5A on the element 14 product page.

Could someone help me please ?

I have had these for many years and michaelkellett and dang74 are correct, the relays are indeed rated for the higher values but the board both electrically and mechanically (It mounts a bit flimsy to be honest) are not, it would put you and your equipment at greater risk if you used it for mains or anything close to it. Sure you can use it for AC or DC, but stick to no more than 20V (24V psu for control should be perfectly ok)

For better safety look at integrating a SONOFF or SHELLY mains control module and use node red or home assistant on the PI, what are you looking to build?

is this the one you have or the newer one
