CMX60D10

qwertyman — Tue, 01 Sep 2026 08:34:21 GMT

Hi, good day.

May we confirm if the front markings on the two CMX60D10 components being different in size are considered normal?

we have found these two part in one box.

Could you please confirm if this is an acceptable manufacturing variation or a factory defect?

Thank you.

Hi,

this can happen. The version 2506 is older one month, may be this device was wrong placed.

The datasheet:

Allen Bradley PLCs is a big topic. In the US, A-B is the most popular PLC. Contrologix is used for large complex industrial systems. As the name implies Compactlogix is for small to medium manufacturing systems.

hi sorry, what meant was the placement of markings. as you can see on below photo..the left part markins was slightly place lowered. the markings of right part was way higher.

Without a proper "reference grid" in the back and with the shadows on your picture, it's really difficult to see what size difference there is.

Bosch Plena LBB1935 schematic

jsmartins — Tue, 02 Jun 2026 23:11:46 GMT

Hello,

I have two Bosch Plena LBB1935 amplifiers that need repair. On the main bord there are some resistores with burn signs but i will nee the schematic to find the right values. Anyone have the circuit that can share a copy?

Thanks

José Martins

jsm, I am going to assume by your profile points count this is your first visit or your first attempt at interaction.

As the illustrious moderator has pointed out, what you have asked and what you have provided to us reduces the chances of getting what you want.

I have interacted with some pretty bright, knowledgeable individuals on this site. They will share their knowledge and experience to solve a problem. It is not free. It requires an investment.

I invest by providing as much information that i have. What I know. What i don’t know. I hope that the investment increases my chances of getting a response. I don’t guarantee the formula works, but if experience is the measurement, I have had more success than failures.

RE: MMM (Multifrequency, Modulated, and Multi-wave) Ultrasonic Technology

Rick1234 — Thu, 13 Aug 2026 05:39:47 GMT

Abandoning the originally pic'd "clamp-on" type transducers!

That method requires too much ultrasonic energy that way.

Submerging the transducers into the "nucleation chamber" (pipe!) with a direct water contact requires a much lower power demand.

I now don't believe I require the complexity of an MMM ultrasonic paradigm for this "water treatment" setup ..... as the water's path to be treated flows tightly "captive" to the confines of the nucleation chamber affording a uniform nucleation of the minerals passing thru.

My thoughts are to alternately fire the ultrasonic transducers for a uniform nucleation of the water ...... but, without "imploding"!

MMM (Multifrequency, Modulated, and Multi-wave) Ultrasonic Technology

Rick1234 — Mon, 03 Aug 2026 03:32:16 GMT

Hello Element14 community!

My quest is to build an MMM ultrasonic water treatment system for use in the motel and laundromat industries.

Basically, to ultrasonically negate the scaling ability of the minerals in the water before they can form on the inside of the pipes and heat exchangers walls.

The MMM paradigm greatly eases the normally strict mechanical ultrasonic interface to the target load ..... as the MMM generator constantly frequency "sweeps" and "optimizes" its effects on the scaling minerals in the water.

My early thoughts:

PC control to set parameters (power, frequency sweep, modulation, etc) + Adaptive Digital Signal Processor (ADSP) + Ultrasonic Power Driver

Minimum ultrasonic "contact" time with the scaling minerals (calcium & magnesium) during a max. 50 gpm water flow rate = 1.5 seconds

Ultrasonic transducer and horn to be of a "clamp-on" type design (ie: surrounding the water feed pipe)

The main attribute of MMM is its ability to "self-adapt" to any varying physical sonic envelope and load ..... on-the fly! (w/feedback loop sensor)

Its my contention, that in this application, the sonic envelope (pipe) and load (water) is "fixed" and should afford a simpler software implementation script.

Where to start? (Note: i'm day one working with ultrasonics!)

Can anyone recommend a preassembled factory evaluation ADSP board suitable for this application and an ultrasonic power driver board?

Thank-you!

I had assumed "cavitation" was always accompanied by an ending implosion ! : (

With ultrasonics you can have both "stable" and "inertial" cavitation under your control!

For use in my ultrasonic "nucleation" of the scaling minerals, only a stable cavitation is required and has a significantly low power demand.

Likely proprietary. You would have a better response if you post clear photographs of the board and the parts.

Has anyone worked on Integrating with openplotter for AIS ADSB marine Ham band monitoring?

KariR — Wed, 20 May 2026 12:33:57 GMT

I'm interested in replacing my sdr dongles with this kit to integrate AIS ADSB Marine and Ham band monitoring. The capabilities of the kit fit nicely and will allow for simultaneous wideband monitoring over a very wide spectrum

Question: Industrial optocouplers keep failing on-site, what thermal management products can solve this issue?

wanjieyu_. — Thu, 06 Aug 2026 03:36:45 GMT

The optocouplers on our production line control boards work under continuous high-temperature conditions and often suffer breakdowns or signal distortion failures.

Besides standard cooling fans, I’m wondering what mature thermal management products, thermal conductive components or circuit design solutions are available to reduce high-temperature damage.

It would be much appreciated if anyone could share solutions that have been applied in industrial or automotive projects.

SensoredHacker0 — Thu, 06 Aug 2026 18:44:04 GMT

Auxiliary cooling is a hack for design out of spec. dont do that. Better lab testing should reveal such things before they happen.
whether the component is in spec for the environmental conditions, will be defined in the datasheet.
I test failure patterns on all the hardware we use, regardless of spec. To do that, some of the tools I use are small ovens,
thermal cameras, oscilloscopes, function generators, and insulated boxes of various sizes.

Everything will fail.
You should know the conditions where the products you use fail. Maybe its heat. maybe its noise from some other device, maybe high ambient humidity does it.
when your techs show up, after whatever unit fails, do the components seem to work? or is there permanent damage? Is there discoloration? smells? surface texture changes?

I had these relays operate at max load for 24 hours per their rating. The plastic got kinda soft. thats a fail. Others caught fire. testing the spec isnt even abuse.
Ill abuse the crap out of a device to make sure it works as expected every time. we had one last year when some panels installed on a roof in the sun reached 130+ degrees.
nice, we didn't anticipate that. we fixed it by installing a little roof to cast some shade. Thats a hack. I wouldn't point to that install as a proud moment in controls engineering. I cant
say to a customer, hey we normally install these in mechanical rooms, or basements, this whole roof top thing, .. we didn't test for that.

If the ambient temperature is too hot, you may not have anywhere to transport the heat. In that case you may need to consider a Peltier cooling module.

BigG — Thu, 06 Aug 2026 13:18:09 GMT

What do you class as "high-temperature conditions".

Why are you just focusing on thermal management as the sole issue. What sort of isolation do you require. E.g. why not switch to digital isolation.

As such, I'm not sure how I can share any solutions but if I read between the lines it does sound like you want to sell something.

Is this all about CTR's...
