The SeaI/O-430E is a high-density Ethernet I/O module featuring 32 optically isolated inputs. Designed for remote monitoring and control via Modbus TCP, it offers robust electrical isolation, flexible power input, and seamless integration into industrial automation systems..
The SeaI/O-430E is an Ethernet-based digital input module that allows for remote interface of 32 optically isolated inputs, supporting signal ranges of 5–30VDC. With 300V of external isolation and strong channel-to-channel isolation, this module ensures accurate and noise-free signal acquisition—ideal for critical monitoring applications in industrial control, security systems, and automation.
The unit connects through 10/100BaseT Ethernet and communicates using Modbus TCP, making it interoperable with most modern PLCs, SCADA systems, and industrial PCs. For custom development, it supports the SeaMAX API, which offers robust software support across Windows and Linux platforms.
Inputs are accessed via removable 3.5mm terminal blocks, streamlining field wiring and future maintenance. Power is supplied through a 9–30VDC input, compatible with standard industrial power sources.
For field operations, testing, or remote access, the SeaI/O-430E supports the Modbus Connect iOS App—allowing you to view and manage registers and coils from your mobile device.
Need to expand your I/O? The 430E is ready to scale, supporting up to 246 SeaI/O N-series modules through its convenient pass-through connectors.
