Control 32 open-collector outputs via any USB connection with the SeaI/O-540U. The open-collector outputs provide high current sinking over a large operating voltage.

Each open-collector output circuit includes a flyback diode for protection when interfacing highly inductive loads, such as DC motors. Outputs are grouped in eight-bit ports which share high and low voltage contacts via 3.5mm terminal blocks.

The SeaI/O-540U is powered from your 9-30V DC source, or select from a variety of Sealevel power supply options.

Communicate with the SeaI/O-540U using Sealevel SeaMAX API software libraries or use any Modbus RTU compliant device. Sealevel's SeaMAX software drivers and utilities make installation and operation easy using 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-540U integrates a patent-pending SeaLATCH 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.
