electronic design

16 channels analogue/digital/PT100 detector

Design based on MSP430 with LED interface, SD memory. RS232/485. Input chanell /every – PT100 (  2,3 wire) , analog/digital voltage from range 0-12V, current input 0-20mA. Full scale regulation. Resolution of ADC – 10bits. Precision inside refernce with low temperature drift give stabilized measure in temperature range -30+85C.  The board give external slot for industrial SD card which can save log with data along 10 years from 16 channels. Low power design – 10-20mA/12V supply.  Readings data on LED 2*16 characters. Supply of device: 12-24VDC
