Product Short Description
Product Brief Introduction: Optical fibre transceiver unit for Trusted Expander Bus, converts copper differential bus signal into optical signal to extend communication distance between main rack and remote I/O expansion rack.
Technical Specifications
- Transmission Medium: Single-mode optical fibre
Description
- Connector Type: SC connector
- Maximum Transmission Distance: 10 km
- Power Input: Dual 24 Vdc diode OR redundant power
- Bus Protocol: Trusted Expander Bus
Function Features
- Electrical isolation via optical transmission, eliminate ground loop interference
- Dual redundant power input
- Real-time communication fault diagnosis
- Support long-distance distributed I/O layout
Application Scenarios: Offshore platform remote I/O expansion, large chemical plant distributed safety rack connection, geographically separated safety control equipment interconnection
Performance Parameters
- Data Transmission Rate: Match Trusted backplane bus rate
- Power Consumption: Low power design
Material Composition: Metal shielding shell, optical transceiver components, FR4 circuit board
Structure Characteristics: DIN rail mounting independent unit, front panel SC fibre ports, power terminal block
Working Principle: Convert electrical differential bus signal to optical signal for long-distance transmission; receiving unit restores optical signal back to electrical bus signal to maintain communication between racks.
Installation Requirements: DIN rail installation inside control cabinet; optical fibre bending radius comply with fibre specification; avoid fibre exposure to corrosive atmosphere.
Usage Notes: Do not look directly into active optical port; prevent fibre end face contamination; maintain dual power supply for maximum reliability.
