SEA-463M

463M SeaI/O-463M RS-485 Modbus RTU Interface to 96 Channel TTL Digital Interface

Description

The SeaI/O-463M is an RS-485 Modbus RTU interface module providing 96 channels of buffered drive digital I/O. The interface module addresses the 96 channels of I/O as 12 eight-bit ports, each programmable as input or output. Using standard 50-pin IDC ribbon cables, connect up to four industry standard relay racks for PC based control and automation of equipment including sensors, switches, security control systems, and other industrial automation systems. A metal strain relief bracket is included to secure the cables after installation. The SeaI/O-463M is powered from your 9-30VDC source, or select from a variety of Sealevel power supply options.

Communicate with the SeaI/O-463M 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.

To simplify ribbon cable installation, a printed copy of the Ribbon Cable Installation Instructions is included with all SeaI/O-463 orders.
