New 802.11b/g Connectivity for SeaI/O Data Acquisition Modules

Sealevel is expanding our popular SeaI/O data acquisition line with the introduction of new wireless SeaI/O modules at the ISA 2006 exhibition in Houston next month. Choose from a variety of I/O options including Reed and Form C relays, optically isolated inputs, TTL interface to industry standard solid-state relay racks, A/D and D/A functionality. Connect to your SeaI/O network from any 802.11b/g host. All wireless SeaI/O modules offer WEP and WPA encryption for secure, reliable communications.

For maximum configurability, multiple units of any I/O type can be easily daisy chained together using convenient pass-through connectors. Removable terminal blocks are standard, enabling fast, versatile field wiring. SeaI/O modules operate from 9-30VDC, and power can be input via terminal block or DC jack. For easy software integration, application programs or 3rd party software can use the Sealevel SeaMAX library or industry-standard Modbus protocol. Both table mount and DIN rail mounting options are available, and installation is easy using Sealevel’s software configuration tools.

If you'd like complimentary tickets to the ISA 2006 exhibition in Houston, October 17th-19th, please click here and we'll be happy to send you a pass. You can find more details and travel information at www.isa.org/expo.
