  • Specification

The SeaI/O-470U-OEM is designed for embedded or custom applications requiring a mix of analog and digital I/O in a compact, USB-connected format. Built around the high-performance Maxim MAX197 successive approximation-type A/D chip, it provides reliable analog data acquisition with selectable input ranges (0-5V, 0-10V, ±5V, ±10V).

Its digital features include 8 optically isolated inputs for rugged industrial signal monitoring and 8 open-collector outputs for control tasks like relays, alarms, or indicators. Two 12-bit analog output channels make it suitable for signal generation or DAC control. Seamlessly integrate this multifunction module using SeaMAX software, which supports both Windows and Linux environments.

Ideal for applications in automation, test and measurement, and remote monitoring, the SeaI/O-470U-OEM offers flexible, cost-effective expansion with USB ease.
