SeaI/O-570M-OEM is an RS-485 Modbus RTU module offering 8 high-precision 16-bit analog inputs, 8 optically isolated inputs, and 8 Form C relay outputs, designed for embedded and industrial control applications..
The SeaI/O-570M-OEM is a highly versatile I/O module designed to integrate seamlessly into embedded systems. It offers 8 high-resolution 16-bit analog inputs, with a wide range of selectable input voltages, making it ideal for a variety of industrial and test measurement applications. Its analog inputs are software-selectable for ±5V or ±15V, and it can measure floating or ground-referenced signals, such as those from transformers or thermistors.
This module also features 8 optically isolated digital inputs, providing 3500V isolation to protect against electrical noise and transients commonly found in industrial environments. The 8 Form C relays can switch DC loads up to 24W and are configurable for normally open or normally closed operation.
The SeaI/O-570M-OEM uses Modbus RTU over RS-485 for communication, providing reliable long-distance data transmission. Installation is made easy with removable terminal blocks, and it operates over a broad voltage range of 9–30VDC. Expandable up to 246 modules, the SeaI/O-570M-OEM is perfect for building scalable systems.
