Power Board_PCB2 Pressure Transducer (0558038315)

The pressure transducer circuit provides the voltage to operate the pressure transducer and accepts the
gas pressure signal back from the device. This signal is then passed to the Main Control board.
The pressure transducer receives +5 volts DC across J10 pin 3 (+5 VDC) and pin 2 (DC common) The sig-
nal is returned from the transducer on pin 1. This signal is coupled to main control board on J7 pin 19 and
ranges from 0.2 to 4.9 VDC. This is equal to 0 – 100 psi of input pressure.
