Module RS-232 (Modbus RTU) with 32 Open-Collector Outputs (60 Vdc). Power supply 9 ~ 30Vdc, mounting in DIN rail or board, Compatible with Windows and Linux. Expandable I/O up to 246

The SeaI/O-540S is a RS-232 Modbus RTU interface to 32 open-collector outputs. The open-collector outputs provide high current sinking over a large operating voltage. Each open-collector output circuit includes a flyback diode for protection when interfacing highly inductive loads, such as DC motors. Outputs are grouped in eight-bit ports which share high and low voltage contacts via 3.5mm terminal blocks.

The SeaI/O-540S is powered from your 9-30VDC source, or select from a variety of Sealevel power supply options.

Communicate with the SeaI/O-540S using the Sealevel SeaMAX API software libraries or use any Modbus RTU compliant device. 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.
