Embedded Computing for Industrial Control
The RSA-983/D is designed for embedded applications requiring reliable operation in harsh environments. Its fanless design eliminates moving parts, reducing maintenance requirements and increasing system reliability. The wide input voltage range of 9-36 V DC allows the module to be powered from standard industrial power supplies or battery systems. The all-aluminum housing provides effective heat dissipation and physical protection, with an IP65 rating ensuring resistance to dust and water ingress.
Extensive Connectivity and Expansion
With five RS232 ports and one RS232/422/485 port, the RSA-983/D can communicate with a wide range of legacy industrial devices. Six USB 2.0 ports provide additional connectivity for peripherals. The VGA and LVDS display outputs allow connection to operator interfaces and HMI panels. Storage options include SATA, MSATA, and CF card slots, providing flexibility for different application requirements. PCIe and Mini PCIe expansion slots enable the addition of specialized I/O or communication cards.
Application Domains
The NEC RSA-983/D is used in DCS systems for industrial process control, robot and servo system controllers, data acquisition and monitoring stations, manufacturing execution systems (MES), and industrial IoT gateways. Its combination of processing power, connectivity, and rugged design makes it suitable for demanding industrial applications where reliability and flexibility are essential.
