Need Solid Sate Relay Part # 101702 Help Please!!

[DonutMachine]

Long story short – I have a mini-donut machine and one of motors that cycles on and off quit working. The good news is it came with a life time guarantee. The bad news is the guy who built them died years ago and his company disappeared from the face of the earth. I should have asked more questions about who’s life time the guarantee was good for. Through substitution of parts between motors with identical control schemes I have isolated the problem to what looks like a solid-state relay. It’s about 1-1/2” x 1-1/2” square hockey puck style about ½” thick. It has four spade connectors at the corners and a small 4 pin connector in the middle that connects to a position sensor.

The only identifying marks are the numbers 101702 with 9116 under it.

Is this a part #? Is there any way I can find out if this part is still available? What the specs are? Is there any way to figure out who made the part? etc., etc.?

I would really appreciate a little help on this.

Thanx

Date code is probably 16th week, 1991. 101702 almost sounds like a local part number. Otherwise, you'd have a manufacturer's name, UL, etc.

A digital picture or a definition of what it is suppose to do would be the next step. The small 4 pin connector goes to a position sensor and what else? What is the motor's amps and voltage? Just on/off, or does it do reversal based upon position?

This is sounding nasty. A picture would help a lot.

Thanks for the interest Mike and Keith. I’ll get a couple pictures posted within the next few days as soon as I can figure out some place to post them. So please check back.

As noted above the relay has four spade connectors at the corners and a small inline 4-pin connector in the middle of one side.

As near as I can figure (at least for a Mechanical), the relay closes to complete the circuit between two of the spade connectors energizing the gear motor. The shaft of the gear motor completes one revolution when a sensor plugged into the 4-pin connection detects a slot cut into a disc mounted on the shaft and opens the circuit stopping the motor at exactly one revolution. The two additional spade connectors on the relay control the time delay between cycles using a rotary switch to vary the resistance between the connectors.

The 4-pin only goes to a split sensor that reads a slot cut into a disc mounted on the shaft. The motor is 115V AC at 0.75A full load. It just cycles on and off one revolution at a time. No reverse.

I was hoping it was a standard part and that the numbers had some meaning such as a manufacturer code. Or perhaps something similar is available. The whole circuit is 115V AC.

In short, I would need a relay rated for 115V at 1A. It would need a passive sensor and trigger that can open the relay after the shaft completes one revolution. It also needs variable delay between cycles of approximately 1.0 sec to 4.0 sec that can be controlled with an external variable resistor.

Once again, thanks for your help and interest.

The problem is this sounds seriously NON-standard.

Hence the pictures.

Here's how to post them.

The device is probably a variation of a one-shot solid state timer. See:

http://www.amperite.com/Uploads/stb.PDF

(or google "solid state timer") for examples.

They "might" have something close to what you are looking for.

If not, then a solid state timer feeding a latched SSR, with the position sensor hitting an unlatch on the control input might get you there.

Nice idea Mike.

Hi Guys,

Sorry for not getting back sooner. I was out for a couple days. If I did this right the below links should provide pictures. I'm not sure, but I think the 4-wire sensor is probably a light and a sensor that sees the light. That would explain how it can detect a slot cut in the wheel mounted to the shaft. The purpose is so that the donut dropper and flipper which is the same control scheme on a separate motor always return to top-dead-ceter. If the general consensus is that this is a specialty part and there is no way I'm going to get another I will have to figure something else out. Thanks again.

This may seem like overkill, but Mitsubishi makes a PLC for simple applications.

http://www.meau.com/eprise/main/sit...mmable_Logic_Controllers/Alpha_Series/default

It has digital and analog inputs and 8 amp relay outputs. Graphical programming. It could fix your current problem and might possibly be able control the entire dognut maker in the future.

 

[itsmoked]

sreid have you used those? How do you rate them?

Tom; Those pictures are confirming my belief that they are a custom widget that only a manufacturer would have.

It looks to me like you are going to need some sort of device that is off-the-shelf and configurable. Like sreid's suggestion.

Itsmoked,

I've never used this model of Mitsubishi PLC but I have had excellent reliability results with another model (FX Series).
