Sealevel Systems, Inc. announces the new eI/O family of Ethernet digital I/O solutions. eI/O modules provide system designers with a compact, low-cost alternative for monitoring and control and are perfect for a wide variety of applications including process control, facility management, security, and broadcast automation.

Five different I/O models are currently available offering a choice of optically isolated inputs, Reed relay outputs, and Form C relay outputs. All eI/O modules are available in Power over Ethernet (PoE 802.3af) versions to connect to existing PoE networks with power and data provided on one cable, or users can choose DC powered models with 9-30VDC input range. Ready for DIN rail mounting, eI/O modules include a removable plastic clip that snaps onto 35mm DIN rail. The clip can also be attached to any flat surface such as a wall or under a counter.

Communicate with eI/O modules using industry standard Modbus TCP protocol or Sealevel SeaMAX software. The SeaMAX software suite supports the eI/O family and is designed to work with third party applications via the SeaMAX API. Sealevel's SeaMAX software drivers and utilities make installation and operation easy using Microsoft® Windows operating systems. Standard operating temperature range of eI/O modules is 0°C to 70°C, and prices start at $139.


Sealevel Systems, founded in 1986, provides industrial computing solutions in addition to a variety of communications and I/O products including PCI Express and PCI Bus cards, Ethernet serial servers, and USB serial adapters.
