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.
