Sealevel Systems, Inc. announces two new eI/O products available with and without Power over Ethernet. Featuring analog and dry contact inputs and solid state relays, Sealevel's eI/O products provide system designers with a compact, cost effective alternative for monitoring and control. They are perfect for a wide variety of applications including process control, facility management, security, and broadcast automation.

Control and monitor eight 12-bit analog inputs, two optically isolated digital inputs and two solid-state relay outputs via any 10/100BaseT Ethernet connection with the eI/O-170E multifunction I/O module. The module provides eight single-ended or four differential A/D inputs that are software configurable for 0-5V, 0-10V, +/-5V, and +/-10V ranges. The eI/O-170E receives power via a removable spring-clamp terminal block. The lever-style clamping mechanism requires no tools, which simplifies field installation. The module is powered by your 9-30VDC source, or select from a variety of Sealevel power supply options. I/O connections to field wiring are simplified via removable 3.5mm terminal blocks.

Sealevel's eI/O-170PoE has all the features of our eI/O-170E module and is a Class 0 (IEEE 802.3af-2003) Power over Ethernet device. This allows power and data to be transferred over a single CAT5 cable and eliminates the need for an external power supply. With PoE, power can be supplied by power sourcing equipment including PoE injectors (midspans) and switches (endspans). I/O connections to field wiring are simplified via removable 3.5mm terminal blocks.

Sealevel's 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 Windows operating systems. Standard operating temperature range of eI/O modules is 0⁰C to 70⁰C. The eI/O-170E and eI/O-170PoE are available from stock. Call Sealevel Sales for pricing.
