The SeaI/O-430U is a USB-based I/O module featuring 32 optically isolated inputs designed for industrial control and monitoring applications. The optically isolated inputs are ideal for high-voltage isolation and electrical noise protection, with an input range of 5-30VDC.

The module communicates over USB using Modbus RTU for simple integration into control systems. It is powered by a 9-30VDC source, and its removable screw terminals make installation and wiring easier in the field. The SeaI/O-430U integrates the SeaLATCH USB port for secure connections, preventing accidental disconnections.

For system expansion, the SeaI/O-430U can support up to 246 additional SeaI/O N-series modules for large-scale industrial applications. The module can be mounted on DIN rails or used on a tabletop, providing flexibility in installation.
