SeaRAQ™ I/O expansion modules provide unprecedented expansion capabilities for the Sealevel Relio R3 and Relio R4 industrial computers. The 6510 provides eight general purpose 16-bit A/D channels that can be individually configured for 4-20 mA current loop, 0-5V or 0-10V voltage inputs. For maximum protection from damaging external voltages commonly found in industrial environments, the SeaRAQ 6510 expansion board includes 1500 VAC of channel-to-channel and field-to-logic isolation.

The current loop receiver inputs are ideal for interfacing a wide variety of industrial process control and test equipment that use 4-20 mA signaling. The 4-20 mA standard remains a popular method for signal transmission in harsh environments, even over long distances. Current loop has a low sensitivity to electrical noise and is not affected by signal loss over cable runs or interconnections. 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.
