Has anyone ever seen a relay breakout board?
I'm working on interfacing a PLC to an existing machine that's full of relays. I got to thinking that it would be a real time saver if I had a relay breakout board of sorts. What I'm picturing is a relay base (in this case an 8 pin rectangular that plugs into an 11 pin socket) that breaks out into screw terminals.
The effect would be like piggybacking another socket on top of the original.. That would allow pre-wiring a lot of stuff and minimizing downtime, as well as making the modifications easily reversible. So, does such a device exist? |

The existing relays are already in existing sockets. I am looking for a device that can plug into the already existing sockets and provide a new set of screw terminals for me to connect to, so that I can make my connections without disturbing the existing wiring. Also, the sockets in question are rectangular, not round. Like these: http://www.newark.com/idec/sr3b-05/r...00v/dp/13M2994 |

An old defunct relay would probably be fine. Cut off the workings from the relay but retain some connections to solder/attach wires to.

Agree on the usefulness; no, I haven't seen the device. I'd suggest contacting IDEC if that's the actual product and see what they say...issue against there being one would likely be just the holddown and reliability issue that they wouldn't want to have with the interposing part so can guess it never would have made production even if somebody in engineering had the thought. But the unasked question... -- |

So, does such a device exist? Yup. Screw-terminal sockets for certain common relay sizes definitely do exist, I have some here for 2 stypes of "ice cube" relays. Not exactly sure what you are looking for in this piggyback thing, but to just plug an ice cube relay into a socket and have everything connected by screw terminals, you should be able to find those.

OK, you want to REMOVE the relays, and have something with screw terminals that plug in IN PLACE OF the relays? No, I can't think of something quite like that, off the shelf. Those relay sockets look like they take 1/4" or maybe smaller spade terminals, so you can get crimp-type male spade terminals and wire them to terminals strips. So, you could make such an adaptor.

Jon They do use the smaller 0.187" terminals, and I have considered just crimping terminals on my wires and plugging them directly into the sockets rather than crimping ferrules onto my wires (I try to always do that for neatness & reliability) and putting them under screw terminals. That would be a cheaper, almost no-parts solution. It's a problem, though, if I want to put more than one wire on a terminal. |

Pulling out the relays leaves a very tempting place to interface the new controls without ripping out existing wiring. |

So, does such a device exist? Further to the discussion, back in the day, I used to use devices like this https://goo.gl/AcrMwL in my test fixtures. This was a "socket saver" meant to protect the socket from repeated insertions and retractions, while providing convenient points to probe the connections. Something like that with the correct socket configuration and larger tabs with screw terminals or even just plain tabs to accept .250" faston connectors would be great. Would even need the second set of socket receptacles, though that would be a bonus. Perhaps the tabs wouldn't have to come out of the periphery, the could just be .250 (or probably easier, .187) faston tabs where the socket receptacles would be. Sort of a male-male relay adapter. |

So it sould sandwich between the original socket and the original relay. I'm not sure how to describe it any more clearly. |

I've had similar boards made up, populated with the correct terminals for something like $10 - $15 each in quantities of 100 about thirty years ago. The ones I had made were to convert the connections of an odd-ball CD RON drive to accept a standard cable connector. Make up a few hundred and sell them to your competition - - - - |

What you suggested is a relay socket - I really thought I had made it clear that I'm looking for something that will plug into an already existing relay socket, and bring the connections out to screw terminals. For the third, fourth or fifth time: I work on lots of machines that have cabinets loaded with this sort of relay socket (with relays plugged in). I upgrade these machines by adding PLCs in place of the relays. It would be a good thing if I had the ability to just plug my wiring into the already existing relay sockets. Therefore, I'm looking for either a male plug shaped like the relay base that would plug into the socket you linked to and provide a duplicate set of screw terminals; or even better, a socket with the female terminals (and screw terminals) on top and male terminals (like on a relay) on the bottom so that the device could plug int the existing socket , provide an extra set of screw terminals AND optionally have a relay plugged into it. So it sould sandwich between the original socket and the original relay. I'm not sure how to describe it any more clearly. ================ Similar in concept to this? http://www.ebay.com/itm/Octal-Tube-T...-/142407703229 Another near miss: https://www.amazon.com/Lisle-56810-R.../dp/B002MCX6LY I designed and assembled relay logic industrial controls back in the day, but never heard of a test socket or extender for them. -jsw No joy googling Ice Cube Relay plug, base, extender, etc. -jsw Which base configuration? If it is a standard OCTAL base there used to be breakout test plugs for tubes that would do the job. They had either binding posts or fahnstock clips on them. Haven't seen them for YEARS but they used to be readily available from what I remember from my days fooling around with old tube radios. One of the mailorder places I used to deal with carried them, I think. Not difficult to have something custom made in reasonable quantities at a decent price today. |

You might have better luck with a newer OS than my XP and a faster connection. Usually I already know what I'm looking for, such as "ice cube relay" or "Fashoda incident", and get a good hit on the first page. I couldn't find a picture of the old double-ended male fastons with a center screw hole in my junk bins. They were meant as grounding junctions. I also have a few L-shaped male fastons with mounting holes in the second leg, that can be bolted to drilled insulating sheets. These are from the 70's and may no longer be available. -jsw |
