SeaRAQ™ I/O expansion modules provide unprecedented expansion capabilities for Sealevel Relio R3
and Relio R4 industrial computers
. The SeaRAQ 6512 analog expansion board is specifically designed to interface inexpensive thermocouples. To simplify temperature calibration in the field, cold junction compensation is provided on the board.
To protect the host computer from harmful voltage spikes commonly found in industrial environments, the 6512 provides 1500 VAC isolation. For easy, reliable field wiring, the board uses removable, high-retention terminal block connectors and is compatible with type E, J, and K thermocouples.
software drivers and utilities make installation and operation easy using Microsoft Windows
operating systems. Communicate using industry standard Modbus RTU protocol or use the Sealevel SeaMAX API
software libraries from your application program.
