Data Acquisition Modules Offer Open-Collector Outputs

Sealevel Systems Inc. added the Seal/O-530 and Seal/O-549 digital I/O modules to the SeaI/O family of modular I/O.

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 protocol.
