Product Details

SeaRAQ™ I/O expansion modules provide unprecedented expansion capabilities for Sealevel Relio R3 and Relio R4 industrial computers. The SeaRAQ 8520 expansion board adds 16 isolated relay outputs rated for 5-250 VAC and 5-30 VDC. The Form A relays are organized into four banks of four relays, with each bank sharing a common. The relays support a maximum current load of 2A per relay (4A maximum per bank). The SPST relays are normally open and close when energized.

To protect the host computer from harmful voltage spikes commonly found in industrial environments, the 8520 provides 1500 VAC isolation. For easy, reliable field wiring, the board uses removable, high-retention terminal block connectors.

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.
