MDA320 allows you to install (solder) scaling resistors to properly scale the voltage levels of external analog sensors so that the maximum voltage is 2.5 VDC. You can refer to section 8.1.1 of the MTS-MDA manual for details. http://www.xbow.com/Support/Support_pdf_files/MTS-MDA_Series_Users_Manua l.pdf

But each analog sensor have different operating voltage, but the MDA320 can accept voltages from 0 to +2.5 V DC. Can we connect these sensors directly to the analog ports to read the outputs from these analog sensors or we require any interfacing circuits for limiting their outputs?
