The SeaI/O-420M allows reliable control and monitoring in automation environments. With 16 optically isolated digital inputs and 8 SPDT Form C relays, it supports both sensing and switching applications. Inputs and outputs are grouped in four-bit segments with a shared common, simplifying wiring through removable terminal blocks.

This device communicates over RS-485 using the Modbus RTU protocol or can be integrated through the Sealevel SeaMAX API. It supports seamless integration in both Windows and Linux environments. The SeaI/O-420M is enclosed for durability and is powered via 9–30VDC input, suitable for varied industrial setups.

For system scalability, up to 246 additional I/O modules can be added using SeaI/O’s pass-through connectors. The device is ideal for factory automation, SCADA systems, and any Modbus-based application requiring both input sensing and relay control.
