The SeaI/O-420U is a USB-based I/O module offering 16 optically isolated inputs and 8 SPDT Form C relays. The optically isolated inputs are perfect for applications where isolation from high voltages or electrical noise is needed, with an input range of 5-30VDC. The Form C relays provide long-life switching capabilities and can handle DC loads up to 60VDC @ 2A, ideal for controlling a wide variety of devices.
The module communicates over USB using Modbus RTU, ensuring easy integration with computers and control systems. It is powered via 9-30VDC, and removable screw terminals make installation and wiring a breeze. The Sealevel SeaLATCH USB port ensures a secure, metal-to-metal connection with USB cables, preventing accidental disconnections.
For system expansion, the SeaI/O-420U supports up to 246 additional SeaI/O N-series modules, allowing for large-scale industrial applications. The module is housed in a durable enclosure, suitable for industrial environments, and can be mounted on DIN rails or used on a tabletop.
