SeaI/O User Manual
SeaI/O-470 Jumper and Dipswitch Settings Instructions
The SeaI/O-470 module ships factory configured with the D/A outputs set for 0-10V
and current loop mode on the A/D inputs disabled. If you need to enable current loop
mode or set the D/A outputs to 0-5V, you will need to open the enclosure and access
the jumpers (shown on the next page).
NOTE:
Do not perform these instructions with the power connected. Be
sure to follow proper ESD procedures by grounding yourself and the
SeaI/O module.
What you will need:
SeaI/O-470 module
Phillips head screwdriver
Slotted screwdriver
Step 1
Remove the terminal block from the left side and
then remove the two black screws from each side
of the module as shown in the image.
Step 2
On the front right side of the module, wedge a
slotted screwdriver between the top and bottom
halves as shown. Pry upwards – a pem in the top
half must clear the metal lip in the bottom half of
the enclosure.
Jumpers and dipswitch locations are shown on the
following page.
