The SeaI/O-570N is an RS-485 Modbus RTU expansion module designed to add 8 single-ended 16-bit A/D inputs, 8 optically isolated inputs, and 8 Form C relay outputs to your SeaI/O network. It is ideal for data acquisition and control in industrial automation systems..
The SeaI/O-570N is designed for data acquisition and control applications. It includes 8 single-ended 16-bit analog-to-digital (A/D) inputs for measuring a range of signals, including sensor data. The optically isolated inputs provide robust protection against electrical noise, while the Form C relay outputs can be used to control various industrial devices. Designed for use in harsh environments, the module can operate at temperatures ranging from -20°C to 70°C and has a wide voltage range (9-30VDC) for flexibility in different applications. RS-485 connectivity makes it suitable for long-distance communication, while the Metal Straps and RJ45 pass-through connectors provide an easy way to stack and link modules.
8 Single-ended 16-bit A/D Inputs – High-precision analog input for accurate signal measurement.
8 Optically Isolated Inputs – Protects your system from electrical surges and ground loops.
8 Form C Relay Outputs – Switch DC loads with up to 24W using Form C relays.
RS-485 Modbus RTU Interface – Easy connection to RS-485 networks for seamless integration.
Expansion and Strap Kit – Includes components for easy stacking and cascading of multiple modules.
