Grigsby-Barton Data Sheet

Ask here: GRIGSBY BARTON GB2600-502 94376501 - Electronic Surplus

No record of the company

could only find that they were in arlington heights and their logo. maybe somebody has an old catalog or distributor catalog with some info on this device.

thanks

Well, what does the panel do, according to the schematic wiring drawings?

seems to be some type of switching station.

Post a photo, it will help identify the component. Most likely to be a relay.

here is an image of both sides

its a wide package with dip pins 4 on one end and two on the other. if a relay could be a 2a configuration but no idea about voltage or current rating.

Establish with a DVM tester & segregate the pairs. It appears to be a 12 V relay/switch. Momentarily give 12 V DC to the pair exhibiting resistance of around 250 ohm & listen for some clicking sound. The experiment will help you identify the component. The other 4 leads maybe two switch terminals one NO & the other one NC

The contact current rating may be 1 Amp.

You can refer to Patents 3,668,422 and 3,697,774

You will note the first patent refers to a pair of terminals in the first paragraph of the claims:

"1. A switching circuit for controlling the application of an A.C. source to a load, comprising switching thyristor means having a pair of load terminals and a control terminal and having a bidirectional switching characteristic, said load terminals being connected in series with the A.C. source and the load, control thyristor means having a pair of load terminals and a control terminal, detector means for providing pulses indicative of the zero voltage crossings of said A.C. source, current supply means, means for selectively applying at least one of said pulses to the control terminal of said control thyristor means for triggering the same and for supplying continuous latching current thereto from said current supply means for succeeding cycles of said A.C. source once said control thyristor means becomes conductive, and means for coupling the control terminal of said switching thyristor means to one of said load terminals thereof through the load terminals of said control thyristor. "

All the other GB devices on the surplus electronics as Lyn mentioned on their website indicate their SSR's for 120VAC with 5VDC "coil currents".

We can also see that the device was built in 1971.

On Ebay there are some SSR's with 12 coil currents. (I can't review them here at work because the net nannies blocked Ebay.)

Here is a company selling something similar

http://www.maraindustrial.com/cart/electrical/relays/grigsby-barton-gb-11232-12s-solid-state-relay.html

That's a 12V coil.

On the end with two terminals I would guess the 12VDC coil ( I would check it with a diode function on a DMM since it may be LED driven).

The four terminals could be NO and NC contacts as suggested or it could represent the anodes and cathodes (reversed) of two thyristors as those were typically used in 120VAC SSR's back in the day.

Good luck with your quest !

Just to point out that you should be looking for GB652A-12-1 not 625

Wish to thank you all for your help. will try to test as described. thanks.
