SeaI/O User Manual
Sample Power Calculation
A typical application for SeaI/O products would use one Base module and several N-
series units in a local expansion configuration. In this arrangement, with power
applied to the Base module through either the DC jack or screw terminal connector
and passed-through to the expansion units, attention should be given to ensure the
input power to the Base module is adequate.
Example:
Power
(W)
Base Unit:
SeaI/O-430U

Expansion 1:

Expansion 2:

4.6W
Power
Required
In this application, the Sealevel Item# TR112 “wall wart” power supply is a good
choice since it is low-cost and supplies 24VDC @ 250mA (6W).
NOTE:
A complete listing of recommended power supplies is provided in
the Accessories section of this manual.
