Adapter adds serial comms options to PC/104
Sealevel Systems has expanded its PC/104 product line with the SIO.104+2, a dual-port RS232/422/485 interface adapter.
Serial adapter fits both PCI slots
The latest addition to the popular PCI product line from Sealevel Systems is the Ultra Comm+2.LPCI, a dual-port low-profile PCIbus serial I/O adapter.
The SeaI/O-520 provides eight SPDT high-current Form C relays that can directly switch up to 6A loads at 250V AC and 100V DC.
Additionally, eight nonpolarised 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.
Ordering options allow connection to a host computer via wireless Ethernet (802.11b/g), wired Ethernet, RS485, USB or RS232.
Status LEDs are included to indicate communication, power, and fault conditions.
For connecting I/O, removable terminal blocks are standard, enabling fast, versatile field wiring.
SeaI/O modules operate from 9 to 30V DC, and power can be input via terminal block or DC jack.
Both table mount and DIN rail mounting options are available, and installation is made easy using Sealevel's software configuration tools.
A variety of SeaI/O expansion modules are available offering Reed and Form C relays, optically isolated inputs, TTL interface to industry standard solid-state relay racks, A/D and D/A functionality.
Multiple units of any I/O type can be easily daisy chained together using convenient pass-through connectors.
This expansion capability enables a distributed network to be controlled with even a traditional point-to-point USB or RS232 host connection.
Multiple units can be combined in a local stack or separated up to 4000 feet using the RS485 Modbus RTU expansion interface.
For easy software integration, application programs or third-party software can use Sealevel's SeaMAX library or industry standard Modbus protocol.
SeaI/O modules are housed in rugged metal enclosures suitable for extreme environments.
Standard operating temperature range is 0 to 70C and extended temperature range (-40 to +85C) is optional.
SeaI/O-520 prices start at $289 and product is available immediately from stock.
All SeaI/O products include Sealevel's lifetime warranty.
