SeaRAQ™ I/O expansion modules provide unprecedented expansion capabilities for Sealevel Relio R3
and Relio R4 industrial computers
. The SeaRAQ 8510 expansion board adds 16 channels of isolated digital inputs designed for 3-30 VDC. The inputs are compatible with TTL signal levels.
To protect the host computer from harmful voltage spikes commonly found in industrial environments, the 8510 provides 1500 VAC isolation. Applications include connecting sensors, switches, push buttons, and other low voltage inputs. For easy, reliable field wiring, the board uses removable, high-retention terminal block connectors.
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.
