The SeaI/O-420S module provides reliable control and monitoring of devices through 16 optically isolated digital inputs and 8 Form C SPDT relay outputs. The inputs accept 5–30VDC, and the Form C relays can switch loads up to 60VDC at 2A, ideal for industrial applications such as controlling equipment and alarms.

With easy installation and integration, the SeaI/O-420S operates using the Modbus RTU protocol over RS-232 communication. It is powered by a 9–30VDC source, providing flexibility for various installations. Each I/O port is designed with removable terminal blocks for fast and secure field wiring, making it a practical choice for industrial environments.

For software communication, the SeaI/O-420S integrates seamlessly with Sealevel’s SeaMAX API drivers for both Windows and Linux operating systems, providing a complete solution for control and monitoring. The module can be expanded with up to 246 SeaI/O N-series modules, making it scalable for large systems.
