Unidentified device next to 13A sockets

I have been investigating a church organ that suddenly stopped working. This was rebuilt about 20 years ago using a data cable between the keyboard and the pipe section.

I have found two 13A sockets unused which are live and, just above them, two more which are not. All the electronic equipment is plugged in into the two which are not. Between the two is a box with the device small device in it

Can anyone identify it and advise its purpose. I am thinking some sort of surge protection but cannot identify any similar photos on google of find any identifying marks.

I'll post a photo when I can find out how. Copy/paste, drag n drop and insert don't work. It seems to want a URL but my photos don't have URLs.

    Click on the 'upload' link - after you've picked your picture from your disc it'll upload it and provide the URL...

  • Thanks.

  • To me, quickly, that looks like an SSR, probably. If you can remove the spurious cover and danger notice we can be sure. Where do the thin wires come from - if it is an SSR, these will be the "turn on" signal, while the two chunky brown ones will be the 'relay contacts' to put mains to  the sockets that supply the loads.
    Or, out of context that may be total cobblers.

    Edit - I imagine this sort of thing - but beware that actuation voltage, current handling and terminal layout are all up for grabs with various makes - proceed with care.

  • Thanks. That makes a lot of sense. Now to find where the two thinner wires come from!

  • I expect you will find a lower power switch operated by the organists seat, or something equally weird like it comes on with the light above the music stand that has been unplugged.
    Do let us know, and if you can, post another pic...
    I do remember the rude sniggering at the back of the crowd when someone at work brought in an ancient unit made by British Organ Blowers to look at, that unit, from memory actually needed new brushes on its motor. (They are still going but the name has changed to B.O.B Stevenson Ltd)

  • I am now mighty puzzled.

    The unit looks very likely to be an SSR, as you say. It is controlled by a cable coming out of the main box of electronics which is plugged in into the socket that is controlled by the SSR, so I don't see how it can ever have worked - but it did for 15 years.

    Something very clever is going on as the only cables I can find (the console is on wheels so nothing is hidden), is the power to the console and the data cable. I am guessing that the data cable must also be carrying some sort of discrete ON/OFF signal to switch on the electronics.

  • Surely if the "relay" was of good manufacture it would have a maker's name and terminal identification as well. It does look cheap and nasty. What happens if you join the two thicker brown conductors together? Perhaps the relay turns on the air pump (organ blower).

  • The organ and organist rise up out of a trap in the floor.

  • Or the relay switch is situated at the lectern, so if the organist is overcome with church holy wine, the organ can be easily remotely turned off.

  • Joking apart, there usually is some sort of signalling system or a mirror so the officiant can communicate with the organist who is generally facing away from them.
