EE question - relay DS2E-N-DC12

[RetroNinja]

Hello,
I'm trying to help an older neighbor. Does anyone know details on relays? The DS2E-N-DC12-C shown in the pic has some amps and volts listed. I cannot find this exact relay but I can find a DS2E-N-DC12.

OLD DS2E-N-DC12-C
0.3A 125VAC
0.3A 110DC
1A 30DC

NEW DS2E-N-DC12
0.6A 125VAC
0.6A 110DC
2A 30DC

So my question is do the ratings matter? Are they the trigger amps or are they the max amps the relay supports?

• I kinda think they are max amps, with the 12V rating being the trigger, so it would be safe to use them.
• I also kinda think the 3 ratings are the same, it just depends on the power applied (125VAC vs 110DC vs 30DC, but all equal about 30W of power ). Meaning the actual hardware is rated (i.e. 'thick enough') for roughly 30W

But I don't know.

Markings on a relay usually indicate the contact ratings, so I think you are correct

You can find the datasheet of a very similar relay on Mouser, the part number is almost the same, "N" and "S" should stand for "normal" and "high sensitivity" but it's practically the same relay

The datasheet confirms that 12V is the coil voltage and 2A 30VDC is the switching capacity, so I wouldn't worry about it and replace it with the higher rated one
