Reliable RS-485 Modbus RTU interface board featuring 16 optically isolated digital inputs and 16 durable Reed relay outputs, ideal for industrial control applications..
The SeaI/O-410M-OEM provides seamless integration of 16 isolated inputs and 16 Reed relay outputs over an RS-485 Modbus RTU interface. Designed for industrial-grade control systems, this OEM module supports direct input voltage ranges between 5-30VDC, making it versatile for various digital signal sources. The Reed relays are optimized for low-current switching tasks, ensuring long-term reliability.
For software integration, the device supports the open Modbus RTU protocol and Sealevel’s own SeaMAX API libraries, compatible with Windows and Linux platforms. This allows flexible programming and rapid deployment in automation systems.
Each group of 4 I/O lines shares a common ground for simplified wiring, and removable terminal blocks make installation and maintenance easier. The unit draws minimal power and operates reliably across a broad temperature range. Optional expansion through SeaI/O N-series modules makes this board highly scalable for large installations.
