SeaI/O Manual 29
Designed using the Maxim MAX197 successive approximation-type A/D chip, the SeaI/O-470
provides eight differential or 16 single-ended 12-bit inputs. The A/D inputs can be individually
configured for sensing 4-20mA current loop signals. Additionally, the module provides two 12-
bit D/A output channels, eight optically isolated inputs, and eight open-collector outputs, ideal
for driving 24V devices commonly found in industrial environments. Perfect for a variety of data
acquisition/control and test & measurement applications, the SeaI/O-470 includes removable
screw terminals, which simplify field-wiring connections.
USE EXTREME CAUTION!
High voltages will be present on the SeaI/O family of products when high voltage is
connected. Never handle the printed circuit board when high voltage signals are connected
to the board.
