Description
Control and monitor 16 optically isolated inputs and 8 Form C (SPDT) relay outputs via any USB connection with the SeaI/O-420U. Inputs can range from 5-30VDC, while the Form C relays switch up to 60VDC @ 2A. Inputs and outputs are grouped in four-bit segments that each share a common for easy wiring via removable 3.5mm terminal blocks. The SeaI/O-420U is powered from your 9-30VDC source, or select from a variety of Sealevel power supply options.
Communicate with the SeaI/O-420U 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-420U 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.
