Product Features

• High Reliability: Adopts industrial-grade design, capable of stable operation in harsh environments.
• Modular Design: Compact size and light weight, facilitating quick plugging, unplugging and replacement in the system.
• Flexible Configuration: Each output channel can be independently programmed, supporting custom alarm logic and voting logic.
• Environmental Adaptability: Equipped with waterproof and dustproof design, suitable for various industrial on-site environments.

Structure and Composition

• Core Components: Including circuit board, relay, connector and terminal block.
• Interface: Usually equipped with M12 circular connector, or provides standard DIN rail mounting interface according to system requirements.
• Indicator Lights: Equipped with status indicator lights (such as OK LED, Bypass LED) to display module operation status and fault status.

Application Fields

• Power Industry: Protection and control of generator sets, steam turbines, compressors, etc.
• Oil and Gas: Monitoring of pumps, compressors, turbines and other equipment.
• Industrial Automation: Used for vibration monitoring, motor protection, process control, etc.
• Aerospace: Key monitoring and protection of engines and transmission systems.

Installation and Maintenance

• Installation Method: Supports rack mounting (such as 3500/05 rack), panel mounting or wall mounting. Usually insert into the designated slot of the rack to ensure the buckle is locked.
• Debugging: After power-on, the OK LED is always on. It is necessary to configure communication protocols, alarm thresholds and other parameters in the 3500 System Configuration software.
• Maintenance: It is recommended to perform communication interface inspection every 12 months, and clean the terminals with anhydrous ethanol every 6 months in salt spray environment. When the indicator light is abnormal, first check the communication link or firmware version.
