This unit broke just under 6 months and I took it apart to see why. I see a traces of magic smoke, but I can't find the source. No cracks, no burns, just some black stuff on some components. Main processor MC9S08 is a 8-bit MCU by Freescale, there is also AD7795 6-Channel, low noise low power, 24-/16-Bit ?-? ADC with on-chip in-amp and reference and other misc. ST, AD and TI components. The PSU driver chip is TOP 246 PN. It has custom LED display with pretty bright red, yellow and green LED's.
I thought this supposed to withstand for years, because it controls industrial processes, but I guess I was wrong.
