2) Use a regulated DC power supply for DC power. When a simple direct current such as full
wave rectification must be used, attach a smoothing capacitor to reduce ripple as much
as possible and heed the following:
a) Instantaneous output voltage including ripple must always be within the following
ranges:
• DC Input Modules: 9 to 30 VDC
• DC Output Modules: 10.2 to 30 VDC
• Relay Output Modules: 100 m to 125 VDC
b) Output voltage must not exceed the following voltages, even momentarily, including
when the power is turned ON or OFF.
• DC Input Modules: 30 VDC
• DC Output Modules: 30 VDC
• Relay Output Modules: 125 VDC
c) Attach a noise filter in front of the rectifying element to prevent surge voltage from
rushing inside.
d) When connecting electromagnetic contactors to the output of full wave rectifier cir-
cuits, prevent surge voltage by attaching a surge suppressor between the output on
the I/O Module side of the electromagnetic contactors.
