New Family of USB Data Acquisition Solutions

Date: 12/13/2006

Sealevel Systems Inc. announces the SeaDAC family of USB compatible data acquisition and control modules designed to meet the core needs of a variety of applications including test and measurement, security, and industrial control. SeaDAC modules connect to any computer?s USB port and offer choices including Reed and Form C relays, optically isolated inputs, TTL interface to industry standard solid-state relay racks, A/D and D/A functionality.

The first module released, the SeaDAC MIO-26, offers a powerful combination of I/O including 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 SeaDAC MIO-26?s eight open collector outputs are ideal for switching 24V devices commonly found in industrial control applications.

For easy software integration, application programs or 3rd party software can use Sealevel?s SeaMAX library or industry standard Modbus protocol. A variety of helpful diagnostic utilities and sample programs are included.

SeaDAC modules are housed in rugged, attractive plastic enclosures and include a highly-retentive USB type B connector to prevent accidental disconnection. Standard operating temperature range is 0?C to 70?C and extended temperature range (-40?C to +85?C) is optional. The SeaDAC MIO-26 is priced from $479 in small volume quantities and product is available immediately from stock.
