Sealevel Systems Inc. added the Seal/O-530 and Seal/O-549 digital I/O modules to the SeaI/O family of
Sealevel Systems Inc.'s SeaI/O-540's 32 open-collector outputs are
well-suited highly inductive loads such
as dc motors. The SeaI/O-530 combines 16 optically isolated inputs with 16 open
collector outputs. The non-polarized inputs can monitor 5-30V dc 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 on
both modules, enabling fast, versatile field wiring.
Both SeaI/O modules are housed in a rugged, metal enclosure and are also
available in board only versions, which allow easy integration into OEM
systems. The modules feature a standard operating temperature range of -25 to 85C and an extended
temperature range -40 to +85C is available. Both the SeaI/O-530 and SeaI/O-540
are powered from your 9-30V dc source and you can select from a variety of
Sealevel power supply options.
SeaI/O modules are useful for process control, data acquisition, broadcast
automation, security and facility management. Multiple units of any I/O type
can be daisy chained together using RJ-45 pass-through connectors or screw
terminals. 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 the Sealevel SeaMAX library or industry standard Modbus
A bold, gold, open-air coupe may not be the ticket to automotive nirvana for every consumer, but Lexus’ LF-C2 concept car certainly turned heads at the recent Los Angeles Auto Show. What’s more, it may provide a glimpse of the luxury automaker’s future.
The complexity of diesel engines means optimizing their performance requires a large amount of experimentation. Computational fluid dynamics (CFD) is a very useful and intuitive tool in this, and cold flow analysis using CFD is an ideal approach to study the flow characteristics without going into the details of chemical reactions occurring during the combustion.
