Isolation must be maintained between the analog and digital circuits of the
PID module to minimize electrical noise interference. Therefore, separate
power supplies must be used for the analog +15V dc supply and for the
digital +5V dc supply.
The requirements for the customer +15V dc power supply and for the
optional +5V dc power supply are listed in Table 2.E and Table 2.F,
respectively.
