SeaI/O-OEM Boards, An Alternative to Bus-Based I/O Expansion

Fifteen I/O configurations are currently 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, and RS-232/422/485 serial connectivity. Multiple units of any I/O type can be easily daisy-chained together using convenient pass-through connectors. This expansion capability enables a network of SeaI/O modules 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 Sealevel’s SeaMAX library or industry-standard Modbus protocol.

Field removable terminal blocks are standard, enabling fast, reliable field wiring. The modules operate from 9-30VDC, and power can be input via terminal block or DC jack. Each SeaI/O-OEM board includes metal standoffs for easy mounting in any enclosure or cabinet.

Standard operating temperature range of SeaI/O-OEM modules is 0°C to 70°C and extended temperature range (-40°C to 85°C) is optional.
