Special Features
Specification
The SeaI/O-410S-OEM is a versatile Modbus RTU I/O interface offering 16 optically isolated digital inputs and 16 Reed relay outputs, ideal for controlling low-current devices such as alarms, solenoids, and lights. Its inputs support a wide voltage range of 5–30VDC, with optical isolation to protect sensitive equipment from noise and electrical transients.
The Reed relays (Form A) provide long-life switch closures and can handle low-power AC or DC loads. The module is powered by a 9–30VDC source and communicates using the industry-standard Modbus RTU protocol over RS-232. It integrates easily with Sealevel's SeaMAX software drivers, enabling smooth integration with Microsoft Windows and Linux systems.
The SeaI/O-410S-OEM’s modular design allows for system expansion, supporting up to 246 SeaI/O N-series modules, making it a flexible choice for large-scale control and monitoring systems.
