    Evening gents,

    I recently got my hands on an old Siemens MultiRanger 100 single level monitor/controller, and I decided to take it apart to see whats inside.

    The photos of the disassembled unit can be found here,


    There were 3 main boards inside,

    1) The motherboard

    2) The AC power supply

    3)The display board

    Is there any way I can find any more information regarding any of the boards or any of the components on the boards? I've tried googling some of the the numbers on the boards without to much success.

    Are there any components on any of the boards that might be worth salvaging? The LCD display seems very nice.

    What do you guys think?

    A Google search took me to here..... http://support.automation.siemens.c...objaction=csview&extranet=standard&viewreg=WW

    which has the owner's manual in pdf. No info on the internal circuits, but all you would need to hook it up and use it. On interesting point is that there is 315 volt pulse sent to the transducer. Siemens is one of the many, many companies that guard their internal information with maximum effort. Typical answer when requesting information is, "Send it to us. We'll fix it for $$$."
