RS-485 Modbus RTU Interface to
16 Form C Relay Outputs
The SeaI/O-450M provides 16 SPDT Form C relays. Each relay output is rated for switching up to 60VDC @ 2A. Connection to the host device is made via an RS-485 connection. The SeaI/O-450M is powered from your 9-30VDC source, or select from a variety of Sealevel power supply options. Communicate with the SeaI/O-450M 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. Get a jump start on your digital I/O development with The Digital I/O Handbook that will provide helpful information that you will use again and again.
