Description
Bently 3500 22-01-01-02
Technical Specifications
- Module Type: Transient Data Interface (TDI)
- Network Interface: 100Base-FX Multi-mode Fiber Optic
- Connector Type: MT-RJ female connectors
- Maximum Cable Length: Up to 1300 feet (400 meters)
Functional Features
- Electrical Isolation: Fiber optic connection completely eliminates ground loop issues and protects the monitoring rack from high-voltage transients in the control room.
- EMI Immunity: Ideal for installation near large motors, variable frequency drives (VFDs), or high-voltage switchgear where copper Ethernet would suffer from severe noise.
- Long-Distance Transmission: Supports high-speed transient data transfer over significantly longer distances than copper cabling.
Application Scenarios
Used in power generation plants, petrochemical facilities, and heavy industrial sites where the monitoring rack is located far from the control room or in areas with extreme electromagnetic interference.
Performance Parameters
- Operating Temperature: -30°C to +65°C
- Storage Temperature: -40°C to +85°C
- Humidity: 95% non-condensing
- Data Rate: 100 Mbps
Material Composition
Precision optical transceivers and high-quality MT-RJ fiber connectors. The internal PCB is heavily shielded to protect the optical-to-digital conversion circuitry.
Structural Characteristics
Identical physical footprint to the standard TDI, but the front panel features MT-RJ fiber ports instead of RJ-45 copper ports.
Working Principle
Converts digital transient data from the rack backplane into optical light pulses, transmitting them over multi-mode fiber to a remote network switch or host computer.
Installation Requirements
Must be installed in Slot 1. Fiber optic cables must be handled with extreme care to avoid bending beyond the minimum bend radius, which can cause signal loss.
Usage Notes
Ensure the correct fiber optic cable type (multi-mode) and connectors (MT-RJ) are used. Keep fiber connectors clean and free of dust to maintain signal integrity.
