The SeaI/O-430U offers 32 optically isolated inputs for industrial control and monitoring, communicating via USB using Modbus RTU. It features Sealevel SeaLATCH USB port for secure connections and is ideal for sensors and other control systems requiring voltage isolation..
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.
