SeaRAQ™ I/O expansion modules provide unprecedented expansion capabilities for Sealevel Relio R3 and Relio R4 industrial computers. The SeaRAQ 6511 analog expansion board is specifically designed to interface RTDs (Resistance Temperature Detectors). RTDs offer a wide temperature measurement range, good accuracy, repeatability, and long-term stability well-suited to industrial applications.
To protect the host computer from harmful voltage spikes commonly found in industrial environments, the 6511 provides 1500 VAC isolation. For easy, reliable field wiring, the board uses removable, high-retention terminal block connectors and is compatible with thin film, wire-wound, and coiled element sensors.
Sealevel’s SeaMAX software drivers and utilities make installation and operation easy using Microsoft Windows and Linux operating systems. Communicate using industry standard Modbus RTU protocol or use the Sealevel SeaMAX API software libraries from your application program.
