Industrial 4Ch RS-232 Serial To Fiber Converter, SFP Port 12~48VDC
Power Input
Industrial Multi-Channel RS-232/422/485 Serial to Fiber Converters
Overview:
The E-link LNK-IRS series represents a cutting-edge
industrial-grade multi-protocol conversion platform, specifically
engineered for high-density serial communication requirements. This
advanced fiber optic converter supports flexible channel
configurations including 4-16 port RS232 interfaces, 4-16 channel
RS485 connections, and 2-8 channel RS422 communications, with
hybrid operation capabilities for mixed signal environments.
Featuring innovative modular architecture, the system enables
customized channel combinations such as 8RS232+8RS485,
8RS232+4RS422, or 8RS485+4RS422 configurations, providing
unparalleled flexibility for complex industrial automation
networks. The compact DIN-rail optimized design ensures
space-efficient installation while maintaining robust performance
in demanding environmental conditions.
Through its advanced fiber optic conversion technology, the system
achieves reliable transmission distances up to 2 kilometers using
multimode fiber and extends to 20 kilometers with single-mode fiber
infrastructure. This optical transmission methodology completely
eliminates electromagnetic interference, ground loop issues, and
lightning-induced damage, ensuring maximum data integrity and
communication security.
The converter delivers comprehensive electrical isolation between
all serial channels and fiber optic links, providing superior
protection for connected equipment in electrically noisy industrial
settings. Ideal for large-scale deployment in factory automation,
process control systems, intelligent transportation networks, and
professional lighting control applications, this high-density
solution establishes new standards for reliability in
mission-critical serial communication infrastructure.
