Thread: BS2-i industrial

  1. #1

    Default BS2-i industrial

    We are working on an application that requires us to use the BS2-i
    (Industrial temp range version), all other components must be able to
    tolerate sub zero weather conditions as well. It now appears we may need to
    use some 40-pin stamps as well, are there any plans to produce a 40 pin
    stamp in the industrial version? any alternatives?

    How about adding a small heater to keep the BS2 above 40F?

    That would not be feasible, and would also require adding a cooling system
    for the units going to Arizona.
    This is in an industrial environment, temps can vary toward either extreme,
    and the specifications for the contract call for ALL components to be
    Industrial temp range rated. The BS2-industrial meets these, but it would be
    a lot easier to use a single 40 pin version than to have to use 2 or 3 - 24
    pin devices.

    If current allowed, you could use nicad(warped around ceramic) wire to heat,
    the new cooling electronics (same used for cpu heat sinks) for cooling and
    temperature circuit to cut in the correct source(heat/cool) when needed..

    Let me restate this, the contract calls for ALL components to be rated for
    the Industrial or Military temp range.
    This means using LM117 or LM217 regulators instead of the commercial LM317,
    LM139 or 239 comparators instead of LM339, LM124 or LM224 OP-amps instead of
    the more common LM324, - optoisolators et.al.
    The BS2-i meets the specs but the BS2, BS2-IC, and BS2p-40 do not.
    It is not in my power to re-write the specifications of the contract to
    state that heating and cooling systems will be installed at all locations to
    accommodate commercial temp rated components.

    Some of the cpu coolers cool on one side then if you reverse the polarity
    they heat on that side. They can be thought of as a heat pump. They simply
    pump heat from one side of the device to the other.

    Do they have to be Stamps? Sorry to be sprouting heresy, but roll your own
    with a Basic compiler and industrial rated components. We routinely build
    equipment (PIC based and otherwise) that has to work to -40 or -50C with no
    problems at all.

    As an aside, do consider the use of the LM29xx series instead of LM139 or
    LM124 - they are automotive rated components that are spec'd from -40 to
    +85C. Again - we use lots of them in our products that have to work both
    hot and cold. Look at the LM2901, 2902, 2903, 2904.

    Hi Lonnie,

    I think you might be able to buy the OEM interpreter chips in the
    industrial temperature rated packages. (call/email parallax?).

    http://www.parallaxinc.com/html_file...terpreter_chip
    s.asp Then you would have to supply the eeprom and the regulator etc
    etc and a circuit board, or you could use one of the OEM circuit
    boards.

    Thanks Dwayne & Tracy, I may have to resort to using extended temp versions
    of a pic and pbasic interpreter et.al. It would be nice though if parallax
    would do a 40 pin version of the BS2-i (save me the trouble). And yes, I do
    utilize the 29xx parts at times, there specs fall between those of the LM1xx
    and LM2xx devices and are sometimes easier to find.
