The SeaI/O-450U provides 16 SPDT Form C relays that can be easily controlled from your computer’s USB port. Each relay output is rated for switching up to 60VDC @ 2A. The outputs are grouped in four-bit segments that each share a common for easy wiring. The SeaI/O-450U is powered from your 9-30VDC source, or select from a variety of Sealevel power supply options.
Communicate with the SeaI/O-450U using industry-standard Modbus RTU protocol or use the Sealevel SeaMAX API software libraries from your application program. Sealevel’s SeaMAX software drivers and utilities make installation and operation easy using Microsoft Windows and Linux operating systems.
Expand your I/O network with SeaI/O N-series products. SeaI/O modules are available with Reed and Form C relays, optically isolated inputs, TTL interfaces, A/D and D/A functionality. Up to 246 additional expansion modules can be added using convenient pass-through connectors.
The SeaI/O-450U integrates Sealevel’s SeaLATCH locking USB port, which is fully compatible with standard USB cables. When used with the included USB cable with a SeaLATCH USB type B connector, the metal thumbscrew provides a secure connection to the device and prevents accidental cable disconnection.

USB450U: Modernizing equipment utilizing Sea I/O 450u
Utilized the 450u as a central relay/solenoid control box as part of modernizing a semiconductor manufacturing tool; bringing the system up to date with modern electronics and software (PC / MS Visual Studio VB.NET 2010). Tool now exceeds original performance metrics and is a true workhorse. Ease of use related to field wiring and software control as well as small footprint and solid build standards and reliability made the 450u a great choice. Would definitely recommend / use in additional projects.
