Sealevel Systems (Liberty, SC) has expanded its SeaI/O family of data acquisition devices with the SeaI/O-570 multifunction module. Offering a combination of analog and digital I/O, the SeaI/O-570 modules target a variety of applications including industrial process control, data acquisition, broadcast communications and remote environmental monitoring. Ordering options allow connection to a host device via Wireless (802.11b/g), Ethernet (Modbus/TCP), RS-485 (Modbus/RTU), USB or RS-232.
The SeaI/O-570 provides eight single-ended 16-bit analog inputs, eight optically isolated digital inputs and eight Form C relay outputs. The module’s A/D inputs are independently software selectable for +/-5VDC or +/-15VDC ranges and feature high input impedance, allowing easy connection to a variety of sensors. The eight isolated inputs are rated for 5-30VDC and provide 3500VDC external isolation, while the SeaI/O-570’s eight Form C outputs are configurable as normally-open or normally-closed and can switch DC loads up to 24W.
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 -20°C to 70°C and extended temperature range (-40°C to +85°C) is optional. SeaI/O-570 prices start at $399 and are available immediately from stock.
