New SeaDAC Optically Isolated Input and High-Current Relay USB Module

December 20, 2006

Sealevel Systems, Inc. announces the expansion of the SeaDAC family of USB data acquisition devices with the introduction of the SeaDAC PLC-16H digital I/O module. Offering a powerful combination of high-current Form C outputs and optically isolated inputs, SeaDAC PLC-16H modules are perfect for a wide variety of applications including process control, facility management, security, and broadcast automation.

The SeaDAC PLC-16H provides eight SPDT high-current Form C relays that can directly switch up to 6A loads at 250VAC and 100VDC. Additionally, eight non-polarized inputs can monitor 5-30VDC and provide optical isolation to protect the host computer and other sensitive equipment from voltage transients and ground loops that are common in industrial environments. For connecting I/O, removable terminal blocks are standard, enabling fast, versatile field wiring.

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. Like all Sealevel I/O products, SeaDAC modules are backed by a lifetime warranty.
