Sealevel Systems 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 analogue 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 12bit analogue inputs, two 12bit 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 0-5, 0-10, +/-5 and +/-10V ranges and can be configured for measuring 0-20mA current loop.

The A/D channels feature 5MHz bandwidth track/hold and 100Ksample/s throughput.

The module's D/A channels are independently jumper selectable for 0-5 or 0-10V output range.

Eight digital inputs are rated for 5-30V DC 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), RS485 (Modbus RTU), USB or RS232.

Field removable terminal blocks are standard, facilitating fast, flexible field wiring.

SeaI/O modules operate from 9-30V DC, 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 daisychained 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 RS232 host connection.

For easy software integration, application programs or third-party software can use Sealevel's SeaMAX library or industry standard Modbus protocol.

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

SeaI/O-470 prices start at $469 and product is available immediately from stock.
