SeaI/O 520E-ET Data Acquisition Device

The SeaI/O-520E provides eight optically isolated inputs and eight high-current Form C relay outputs. Inputs can range from 5-30VDC and optical isolation protects the computer and other sensitive equipment from voltage transients and ground loops that are common in industrial environments. The high-current Form C relays can switch up to 6A loads at 250VAC and up to 5A at 30VDC. Form C relays can be wired for either normally open or normally closed operation. The SeaI/O-520E is powered from your 9-30VDC source, or select from a variety of Sealevel power supply options.

Communicate with the SeaI/O-520E using industry-standard Modbus TCP 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.

The Sealevel Modbus Connect app for iOS allows you to access the registers, coils and discrete I/O of your Sealevel Modbus devices and is available on the App Store. Use the app to remotely access I/O in the field or for testing and troubleshooting during application development.

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.

I/O in Action for Autonomous Follower Vehicles

An industry leader in advanced robotic system design, integration, and control serves the defense industry for resupply and MEDEVAC. Their follower vehicles can travel preset paths or be field-programmed to follow an individual's path. The extended temperature (ET) version of the 520E is selected for use in these vehicles due to robust optical isolation and extended temperature tolerance for reliable operation in extreme environments.
