New SeaI/O Multifunction Analog and Digital Combo Module

July 13, 2006

Sealevel Systems, Inc. announces the expansion of the SeaI/O family of data acquisition devices with the introduction of the SeaI/O-470 multifunction module. Offering a powerful combination of analog and digital I/O, SeaI/O-470 modules are perfect for a wide variety of applications including process control, data acquisition, broadcast automation, security, and facility management.

The SeaI/O-470 provides 16 single-ended or eight differential 12-bit analog inputs, two 12-bit D/A outputs, eight optically isolated digital inputs, and eight open collector digital outputs. The module’s A/D inputs are independently software-selectable for 0-5V, 0-10V, +/-5V, and +/-10V ranges and can be configured for measuring 0-20mA current loop. The A/D channels feature 5MHz bandwidth track/hold and 100ksps throughput. The module’s D/A channels are independently jumper-selectable for 0-5V or 0-10V output range. Eight digital inputs are rated for 5-30VDC and provide 300V external isolation, while the SeaI/O-470’s eight open collector outputs are ideal for switching 24V devices commonly found in industrial control applications.

Ordering options allow connection to a host device via Ethernet (Modbus TCP), RS-485 (Modbus RTU), USB, or RS-232. Field removable terminal blocks are standard, facilitating fast, flexible field wiring. SeaI/O modules operate from 9-30VDC, and power can be input via terminal block or DC jack. Both table mount and DIN rail mounting options are available, and installation is made easy using Sealevel’s software configuration tools.

A variety of SeaI/O expansion modules are available offering Reed and Form C relays, optically isolated inputs, TTL interface to industry-standard solid-state relay racks, A/D and D/A functionality. Multiple units of any I/O type can be easily daisy-chained together using convenient pass-through connectors. This expansion capability enables a distributed network to be controlled with even a traditional point-to-point USB or RS-232 host connection. For easy software integration, application programs or 3rd party software can use Sealevel’s SeaMAX library or industry-standard Modbus protocol.

Standard operating temperature range of SeaI/O modules is 0°C to 70°C and extended temperature range (-40°C to 85°C) is optional.
