b) 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:
(1) Instantaneous output voltage including ripple must always be within the follow-
ing ranges:
• DC Input Modules: 9 to 30 VDC
• DC Output Modules: 10.2 to 30 VDC
• Relay Contact Output Modules: 100 mV to 125 VDC
(2) 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 Contact Output Modules: 125 VDC
(3) Attach a noise filter in front of the rectifying element to prevent surge voltage
from rushing inside.
(4) When connecting electromagnetic contactors to the output of full wave rectifier
circuits, prevent surge voltage by attaching a surge suppressor between the
outputs on the I/O Module side of the electromagnetic connectors.
