Introduction
Sealevel eI/O™ modules offer powerful data acquisition solutions that are perfect for a wide range of
applications and environments with easy interfacing to computers, controllers, and PLCs. eI/O modules are
available in various digital and analog I/O configurations. Each eI/O model is designed for maximum
flexibility and easy field wiring.
For easy software integration, application programs or 3rd party software can use the Sealevel SeaMAXTM
library or industry standard Modbus TCP (Ethernet) protocol.

eI/O Module Common Features
All eI/O modules include the same power connector on the side of the unit. All models use the same style
of 3.5mm pitch screw terminals on front for connection to field devices.
Status LEDs are also included on the front of all eI/O modules to indicate the following information:
•Power (Green) – Lights when power is applied to the module.
•Act (Green) – Light blinks when Modbus/TCP activity is present or when new firmware is
being downloaded.
