Question about piface digital 2

acca

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 ?

    The relays may be capable of working at 250V but the board probably is not.

    You would need to see the underside of the board (if truly good for mains switching you would expect to see slots machined in the pcb under the relays to provide isolation from the signal circuits).

    But it has exposed terminals and poor mechanical fixings to the Pi board so I would not consider it safe in any circumstances.

    It would be OK with 20V .
