RS-232 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-420S. Inputs can range from 5-30VDC while the Form C relay outputs can switch up to 60VDC @ 2A. The SeaI/O-420S is powered from your 9-30VDC source, or select from a variety of Sealevel power supply options. Communicate with the SeaI/O-420S 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.
