Control 32 open-collector outputs via any USB connection with the 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 540U is powered from your 9-30V DC source, or select from a variety of Sealevel power supply options.

Communicate with the 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 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.
