32 Open-collector Outputs
The SeaI/O-540 provides 32 open-collector outputs. Each open-collector output circuit includes a flyback diode
for protection when interfacing highly inductive loads, such as DC motors. Outputs are grouped into four eight-
bit ports which share high and low voltage contacts via 3.5mm terminal blocks.
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 is connected. Never handle the printed circuit board
when high voltage signals are connected to the board.
