GE 8521-EB-MT PAC8000 Ethernet Bus Interface Module

Description

• Environmental and Physical Parameters
  • The operating temperature range is -20°C to 60°C, and the storage temperature range is -40°C to 85°C, adapting to temperature fluctuations in indoor control cabinets and outdoor industrial sites.
  • It has a compact structure, with a standard industrial module size that fits DIN rail installation, facilitating assembly into various control cabinets and saving installation space.
  • It uses industrial-grade metal casings, which have strong anti-vibration and anti-electromagnetic interference capabilities, ensuring that data transmission is not affected by the surrounding industrial equipment.

Function Features

• Dual Core of Communication and Protection

  While completing high-speed data transmission, it integrates multiple equipment protection functions. It can monitor faults such as overcurrent, undercurrent, overvoltage, undervoltage, phase loss and single-phase grounding of power equipment. Once an abnormal condition is detected, it can quickly send out fault signals and trigger protective actions to prevent damage to transformers, lines and other key equipment.

• Stable and Reliable Redundant Design

  It is designed with LAN redundancy, which can automatically switch to a standby communication path when the main communication link fails. This redundant design avoids communication interruptions caused by single-point failures, ensuring the continuous operation of the industrial control system and improving the stability of the entire communication network.

• Convenient Fault Diagnosis and Monitoring

  It is equipped with LED indicators that can visually display the module’s power supply status, communication connection status and operating status. It can quickly feed back fault information to the upper-level control system. Maintenance personnel can locate problems such as communication failures or equipment abnormalities in a short time, reducing the difficulty and time of troubleshooting.

• Strong Adaptability with Modular Expansion

  It adopts a modular design, which can be flexibly combined with different types of I/O modules. Users can increase or decrease the number of connected modules according to the scale of the project and functional requirements. It can be seamlessly integrated into existing PAC8000 series control systems without the need for large-scale modifications to the original system, enhancing the adaptability of the system to different application scenarios.
