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 make-your-own Star Wars Sith Lightsaber hilt is heftier and better-looking than most others out there, according to its maker, Sean Charlesworth. You can 3D print it from free source files, and there's even a hardware kit available -- not free -- so you can build one just in time for Halloween.
