Default Replacement Relay needed Diamond H Controls

Hi, I have a kiln that is buzzing and I have narrowed it down to the relay, its a Diamond M controls number BW240A02 147, does anyone know a supplier that still stocks these or know of a direct replacement? thank you for any help received.

Hi Paul

Welcome to the forum.

Any chance of a picture of the relay?

Cheers

Is it possible that it is Diamond H and not M?
If so, Heatrod in Bolton own the brand and do a range of process control relays and contactors.
Otherwise show us a picture, relays are often generic.

That's more like a Contactor

Might pay you to rewire if for something current.

Cheers

That confirms it's Diamond H, have you contacted Heatrod?

You don't say what part of the kiln is buzzing and if the kiln works or not.

I work in the Switchboard (Industrial Motor Control) sphere, so may be able to help.
What sort of connections are on the relay? - Are they 1/4" tabs (faston) or does it have a plug-in base? or is it soldered in?
Looking at the ratings on the can, there are a number of modern relay you could replace it with - Finder, ABB, Schneider to name a few.
If you can give details of connection and mounting I can suggest a replacement for you.
If you don't have access to a wholesaler, I could get one for you also.
Regards.
