Overview

The SeaI/O-440M provides 32 SPST Form A dry contact Reed relays. Reed relays offer long life performance and fast response time. Each relay can switch up to 60V DC @ 500mA. Connection to the host device is made via RS-485. The SeaI/O-440M is powered from your 9-30V DC source, or select from a variety of Sealevel power supply options. Communicate with the SeaI/O-440M using the 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.
