The SeaI/O-470S-OEM is an RS-232 Modbus RTU interface module that offers analog-to-digital (A/D), digital-to-analog (D/A), and digital I/O (DIO) functionality, ideal for industrial automation and data acquisition applications..
The SeaI/O-470S-OEM combines analog and digital functionality in one versatile device. It features 8 differential or 16 single-ended A/D inputs for measuring various sensors like temperature or pressure, with support for current loops. The 2 D/A channels can output precise analog signals to control devices like actuators.
This unit also includes 8 optically isolated inputs for enhanced protection and 8 open-collector outputs capable of switching high-current loads, such as relays or industrial machines. The device operates over RS-232 Modbus RTU communication, which makes it compatible with a wide range of control systems, and integrates seamlessly into your existing industrial setups.
8 Differential/16 Single-Ended A/D Inputs – Software-selectable for 0-5V, 0-10V, +/-5V, and +/-10V ranges, and supports 4-20mA current loop configuration.
2 D/A Output Channels – 12-bit resolution, jumper-selectable for 0-5V or 0-10V output ranges.
8 Optically Isolated Inputs – Rated for 5-30VDC with 300V external isolation for reliable protection.
8 Open-Collector Outputs – Can sink up to 580mA, suitable for controlling industrial devices like motors and valves.
