Hi

 

I had created a post about a week ago, about relay and enclosures.

 

But i would like to know is there a commercially ready power distribution box, that can have relays(latching) plugged in so that i can control the power to a certain device?

 

I would like to avoid creating a new PCB , with may be 10 relays etc , if such type of boxes are available.

 

I thinking of something similar to trip switch box, but with relays switches instead.

 

All i need to do then is connect my 2 control wires to the desired relay.

 

 

 

 

 

 

Thanks

Regards

DJ

what about something like this...there are plenty of relay board available (some in boxes, or use your own)

Are you looking to control Mains Voltage, or low voltage?

 

For example:

I use these a lot in the access control work I do

Din Rail mounting is commonly used for power switching, with the rail mounted in an electrical panel box.

HI

 

I have seen that before, but i need latching relays.

 

I would prefer there to be one power input and then let is be distributed among the relays.

Thanks

Regards

DJ

Great, can any relay get plugged into such mounts?

Thanks

Yes, pick your relay and the base that match!   Check the catalogs of industrial supply houses, Granger, Automation Direct, etc.

Great, i will check with my local electrical supplier, which is RS electronics.

Your run of the mill 'fuse' boards can have latching relays fitted instead of MCBs.

Great, i think this will be good. This way i can expand as we need more power slots.

 

Thanks

Is the term ‘trip switches’ common in the UK?
Over here, RS components is the place to go to if you want it quickly, but you pay for the privilege. Local automation and electrical supply houses are usually significantly cheaper.

Yes, it's probably the colloquial term that most non-technical people use.

 

The technical terms over here are...

MCB = Miniature Circuit Breaker. Trips on excess load current only, and the similar looking...

RCBO = Residual Current, Breaker Overload. Trips on either excess load current OR excess line/neutral current imbalance

Have a look at stuff made by Schneider Electric.

Sometimes Facebook provides something worthwhile....

 

While I was being 'social' This add popped up in my feed:

 

https://www.amazon.com/dp/B072M4...

 

I might have to order a few of these to see if I can use them in place of some of the Crestron stuff I use currently.

 

THought it might be of use to you.

Devices with a bunch of relays and an Ethernet connection have been sold as commercial products for years.

They are used to remotely power cycle computers.

 

In the PLC world there is also all kind of stuff with the name "remote I/O".
