Re: What is the capacity of this relay?

[mm <NOPSAMmm2005@xxxxxxxxxxx>]

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.

http://www.hascorelays.com/electro_power_consumption.asp

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 Altronix to rate its product according to the Max
switching current or max carry current instead of the rated contact
load?
