    What Are These Parts Called- Where Can I Get Them?

    Actually many of these systems have been converted to PLC, where practical. It also makes trouble shooting a breeze for maintenance personnel. This is why GM instigated the introduction of such a device in the first place.. M.,

    SSR triac not releasing

    SSR's of this nature, especially with this light load do not have a problem, especially if the input switching is contact closure, as opposed to solid state? M.

    Yes that's the neat way do do it, However they MAY have made a Faux pas, I see Orange and Yellow conductors. For N.A., yellow Used to signify a live conductor that originates in another enclosure or source and therefore may be live, since changed to comply with the EU standard from yellow to...

    Another aid to panel building that makes it neat is plastic duct, such as Panduct, available in different sizes, also in many cases where just relay control logic is required, not only can the control relays be of a smaller footprint, IEC etc, but the wire does not necessarily need to be #14 MTW...

    What Are These Parts Called- Where Can I Get Them?

    The fact they are marked CR1/2 etc I am guessing they may be used for control, I have replaced cabinets full of these for systems converted to PLC control etc. Determine the final device they are switching, it may be possible to down size them. I am surprised the absence of wire markers at the...

    There are several terminal strip manuf, the common now is to use DIN rail type as they come in all configurations and can be bridged with a copper strip to make them commons etc. The 4 pole relays are control relays as opposed to contactors, but contactors can be subbed if needed, but you would...

    What is this device inside our well pump controller box?

    As Bluejets, is the level switch circuit working OK? Careful when using a Pencil as a probe, the lead is conductive! M.

    Multiple grounding points in car infotainment

    Automotive wiring usually has a number of Star ground points throughout the chassis. The negate aspect as to ground loops is when a potential exists between one ground or Common point and another, with a automotive chassis, the mass is usually sufficient that virtually no such difference will...

    Creationism/Intelligent Design

    One thing we may never overcome is an evolutionary trait, namely tribalism, it has been estimated that between 1.5m and 2,5m people died Just during the 20 century alone due to all human conflicts! Factor in the ever increasing, exponential, world population and the inevitable world food...

    Identifying Old Components Help

    I have a basement full of similar 'valuable' items. Unless you are into DIY electronics and keep them 'just in case' and you can use them for parts, you will be hard pressed to find a buyer! Even the IC's are probably passe now. M.

    Hacking a flow sensor - Hall Effect Sensor help

    The spec sheet says 3v min 24vdc max. But 3.3v that is pushing the lower limit It is Latching, south pole activated, I have used a few of these series and they are simple to operate, M.

    Replacing upper board with pot. for treadmill motor speed control.

    That reminds me, most that use a pot, that requires that it has to be zero when the units is powered for the speed pot to work. Did you ensure it was zero when you tried it with the Pot? M.

    Replacing upper board with pot. for treadmill motor speed control.

    My go-to source is Digikey, next day air delivery to Canada. There are ones on ebay for $1.50, you could strip the unwanted power components off and just use the 555 circuit only if you just wanted the PWM controller part only to play around with. M..
