RS-485 Modbus RTU Interface to 16 Isolated Inputs /
8 Form C Relay Outputs
Control and monitor 16 optically isolated inputs and 8 Form C (SPDT) relay outputs with the SeaI/O-420M. Inputs can range from 5-30VDC, while the Form C relays provide switch closures up to 60VDC @ 2A. Inputs and outputs are grouped into four-bit segments that each share a common for easy wiring via removable 3.5mm terminal blocks. The SeaI/O-420M is powered from your 9-30VDC source, or select from a variety of Sealevel power supply options. Communicate with the SeaI/O-420M 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.
