Interface 16 optically isolated inputs and 8 Form C relay outputs via any 10/100BaseT Ethernet connection with the SeaI/O-420E. Inputs can range from 5-30VDC while the Form C relay outputs can switch up to 60VDC @ 2A. The SeaI/O-420E is powered from your 9-30VDC source, or select from a variety of Sealevel power supply options.
Communicate with the SeaI/O-420E 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.
