The SeaI/O-440S 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 60VDC @ 500mA. Connection to the host device is made via RS-232. The SeaI/O-440S is powered from your 9-30VDC source, or select from a variety of Sealevel power supply options.
Communicate with the SeaI/O-440S 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.
