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 0.7
Expansion 1: SeaI/O-410N 1.4
Expansion 2: SeaI/O-440N 2.5
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.
