  • Specification

The SeaI/O-470S combines analog and digital interfaces in one compact unit. It offers 8 differential or 16 single-ended A/D inputs that are ideal for precise measurements of sensors like thermocouples and pressure transducers. Additionally, it features 2 12-bit D/A output channels for controlling actuators and other analog devices.

With 8 optically isolated inputs (rated for 5-30VDC) and 8 open-collector outputs capable of sinking 580mA, it’s perfect for applications that require isolating sensitive equipment and controlling high-current loads. The RS-232 interface and Modbus RTU protocol ensure smooth communication with industrial control systems.

The SeaI/O-470S is powered by a 9-30VDC source and supports Microsoft Windows and Linux via SeaMAX software for easy integration.

  • 8 Differential/16 Single-Ended A/D Inputs – Software-selectable for 0-5V, 0-10V, +/-5V, and +/-10V ranges, with 4-20mA current loop support.

  • 2 D/A Output Channels – 12-bit resolution, jumper-selectable for 0-5V or 0-10V ranges.

  • 8 Optically Isolated Inputs – Rated for 5-30VDC with 300V external isolation for added protection.

  • 8 Open-Collector Outputs – Can sink up to 580mA, ideal for switching 24V devices in industrial setups.
