The power supply module transforms the system supply voltage
from 24V to 3.3V DC/5V DC (used for internal I/O bus). It
occupies the left-most slot of the GuardPLC 2000 chassis. The
power supply comes with a lithium battery, which has a four-year life
span, that is used for back-up. Four LEDs indicate the power supply,
battery voltage, and faults.
