What is the capacity of this relay?

Question

I have an Altronix relay module model RBST, which the instructions rate at 6, 12, or 24VDC input, 25ma, and give the contact rating as

2AMP, DPDT, 120VAC

In general wrt relays, does that mean that each pair of contacts is

2amps, or that the total is 2amps?

I see on the relay that is the heart of the module, 1A24VDC 0.5A120VAC and it is a double pole relay. It's a HASCO 9224. Doesn't Hasco know best?

Does the 0.5A refer to the total of the two poles, or is the total

1.0A?

And regardless of the answer to the first 2 questions, the specs seem overblown. Is not the rating of the 2-pole relay, according to HASCO, at most 1 amp at 120vac? So why does it say 2AMP in the specs on the instruction sheet, and on the paper label stuck to the outside of the box**?

If it's wrong, is it just a fluke mistake, or do some companies tend to overrate their devices?

Thanks

**The box was printed with 3 check boxes for different models, but this is a fourth model that isn't one of the three, so there is a paper label says RBST, but that label also gives 3 more lines of specs.

I had the wrong relay model number, that was used in the relay module.

It's a Hasco HS212 6, and it's at this url.

Here is the part that relates to my question:

I'm not sure whether or not it says something different from what is written on the relay itself.

Now it says rated contract load 1A 125VAC

Or did the text on the relay refer to each pair of contacts and 1A refers to both of them.

Max. switching voltage 220V DC 250V AC. Max. switching current 2A Contacting Max. switching power 60W (DC) 125VA (AC) (Resistive load) Max. carry current 2A Rated contact load 2A 30VDC 1A 125VAC

I bought the Altronix item about 2 years ago. Could Hasco have decided the relay was better than they thought it was. Or could they have made them better than they used to, but not changed the printing on the relay.

And is it ok for Altr>I have an Altronix relay module model RBST, which the instructions

"Contact rating" refers to the capacity of the relay *contacts*.  If it says"2 Amps at 125VAC", then you can pretty well bank on that the contacts willhandle "2 Amps at 125VAC".
