Re: relay AC using DC?

he can always solder the wires direct to the correct pins or use a bit of prototype board to mount it, solder the wires then mount in a small plastic box for safety. But apart from that it will give hima an idea of what is available and what he should be looking for.

Most relays require either an electrical cabinet to mount them in, a base fitting (increases costs) that in turn require mounting in or on something. The worst part is usually making sure that soldered wires don't yank off the pins that they are soldered to. One way of getting around that is to solder short flexible wires to the pins then extend them using those plastic blocks which have two screws in them for input output. Sorry so long since i used teh stuff I no longer remember the name. poke wire in one side screw down, then poke wire in other side and screw down .. then you have extended your wire

Re: relay AC using DC?

http://www.grainger.com/Grainger/items/6C873

yea i know way overpriced.

http://www.radioshack.com/product/in...ductId=2049722

50 cents cheaper..am i seeing double?

I may have to go see if the local radioshack has that one and compare the numbers. Otherwise, I'll have to peck the minds of the grainger employees...not a bad idea anyways.

grainger is about 8 miles away, on the other side of the new cowboys stadium from here.

Re: relay AC using DC?

I make it $1 cheaper .. $9.46 - $8.49 .. bar a few cents.

of course that is without taking into consideration time & travel costs

however they look very similar and eitrher would probably do you

(I wasn't aware that Radio Shack was an economical store must be a first~!)

radioshack has one that says 12VDC and 120VAC. but if the clear poly has writing on it, i'l have to look closer and read.

Re: relay AC using DC?

Granger specs
Quote:
Square Base General Purpose Relay, Number of Pins 8, Contact Form DPDT, Contact Current Rating Resistive 10 Amps, Contact Current Rating Inductive 7.5 Amps, Coil Voltage Rating 12 VDC, Coil Current Rating 75 Milliamps, HP Rating @ 120VAC 1/2 HP
Contact Current Rating Resistive 10 Amps,
this is most likely a DC rating

Contact Current Rating Inductive 7.5 Amps

this is most likely an AC rating

Radio Shack

Quote:
Features

* Contacts and Ratings: DPDT 10A at 125VDC

What's in the box

* 1 x 12VDC/10A DPDT plug in relay
As to be expected Radio Shack aren't telling you enough .. although with a double throw you could parallel up the contacts, if you are uncertain
looks like a heavy duty contact anyway from the specs

thats why im not sure. But it looks like the clear piece has the specs lasered on it. I'll have to read it to choose.
