Does anyone have a source for a 48 volt dc input relay?

What contact current? How many contacts? Relay or Contactor? Solid State or Mechanical?
What is the end use for?

Thanks for replying guys.

I found one and ordered a couple today. Here are the specs:

These relays are ideal for use with the Gecko G540 when using a 48V supply. 
These can be used without the need for an additional relay coil power supply.

* Contact Form: SPST
* Contact Rating 20A (Max)
* Coil Voltage 48V
* Coil Resistance 2304 Ohm
* Contact Voltage 240Vac (Max)
* Contact Voltage 28Vdc (Max)
* 0.25" spade connectors for Relay Contacts
* 0.187" spade connectors for Coil Contacts

I'll post the link here for others members in the same situation...

Just got a couple of relays like this, except they're 30A.
I'm building my 1st router and have all the electronics working with a Gecko G540, Keling 48V 7.3A power supply (going directly to the wall), and 3 Keling 3.5A steppers.

Curious about the router and vacuum <-> relay connections. I checked one of the homann wiring diagrams and it looks like all that is needed to connect the router & vacuum to their respective relays is a female socket, and that the relays/router/vacuum all get their power from the same power supply that the G540 & stepper's connect to. Is this correct?

Thanks everyone for the help.

Tulsaturbo,

If you are planning on controlling the router and vacuum from G-code, then the output from your breakout board to the relay coil may need buffering. Does your BOB have relay's on board?

By the way, I'm in BA if you are in Tulsa shoot me a PM.

Hey Steve...

Yup, I'm located in Broken Arrow now over near the Forest Ridge Golf Club.
