Printed Circuit Boards (PCBs)
Analysis Transducer Interface PCB, P/N: 350-17705-011
The two Analysis Transducer ADC PCBs are identical and responsible for controlling most functions
throughout the analysis module. This includes actions performed by the gas inlet, dosing, and sample
manifolds. All transducer and temperature readings from the upper portion of the instrument go
through this board and are changed from Analog to Digital. The analysis transducer interface board is
partially enclosed by a metal barrier to protect its components from radio frequency interference. It is
mounted on the Upper Backplane PCB (P/N: 350-17707-011) at the top of the instrument.
