Key Features

• Quad-Ethernet Connectivity: Outfitted with four independent RJ45 modular jacks supporting Gigabit speeds. This allows engineers to physically separate redundant control networks from SCADA, HMI, or enterprise-level management links, enhancing both security and performance.

• Exceptional Data Integrity: The module employs ECC (Error-Correcting Code) for both its main memory and its static RAM. This hardware-level protection detects and corrects single-bit errors, ensuring the system remains stable in industrial zones prone to high electromagnetic interference.

• Extended Functional Support: The "W" designation signifies that this module includes advanced functional software support, allowing it to handle more complex control logic and specialized industrial communication protocols compared to standard models.

• Proactive Hardware Monitoring: Includes RAS (Reliability, Availability, and Serviceability) features such as an integrated watchdog timer and temperature sensors. These systems monitor hardware health in real-time to alert operators before a failure occurs.

• Direct Hardware Control: Features physical switches for RESET, SHUT DOWN, FUNC, and EXEC, enabling direct manual intervention. Seven onboard LEDs provide instant visual feedback on CPU status and network activity.

• Vital Variable Protection: A 1000 mAh graphite fluoride lithium battery provides backup power to the SRAM, preserving setpoints and critical process variables during a total power loss.
