Sealevel SeaRAQ 16x Isolated Form A Relay Outputs Expansion Module

SeaRAQ I/O expansion modules provide unprecedented expansion capabilities for Sealevel Relio R3 and Relio R4 industrial computers. The SeaRAQ 8520 expansion board adds 16x isolated relay outputs rated for 5V to 250V AC and 5V to 30V DC. The Form A relays are organised 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 energised.

To protect the host computer from harmful voltage spikes commonly found in industrial environments, the 8520 provides 1500V AC 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.
