Industrial 4 Channel RS232 RS485 RS422 Fiber Media Converter 20km
DIN Rail
Model: LNK-GY series
Product Description & Overview
The Industrial 1~4Ch RS232/RS422/RS485 Serial Fiber Media Converter
delivers robust fiber optic
connectivity solutions for critical industrial communication
networks. This versatile media converter
establishes reliable connections between multiple serial devices,
supporting 1 to 4 channels of RS232,
RS422, and RS485 interfaces with flexible port configuration
options. The device enables full-duplex
serial communication over standard duplex fiber optic cables while
offering extended transmission
capability up to 20 kilometers using single-fiber bidirectional
technology, effectively overcoming
distance limitations of traditional copper-based serial
connections.
Engineered specifically for industrial automation applications,
this multi-channel converter features
a compact DIN-rail mountable design that optimizes space
utilization in control cabinets and industrial
enclosures. The hardened construction incorporates advanced
protection mechanisms that significantly
exceed the capabilities of commercial-grade media converters,
including enhanced surge protection,
wide temperature tolerance, and electrical isolation to ensure
stable operation in electrically noisy
environments. These industrial-grade features provide complete
immunity to electromagnetic
interference, ground loop issues, and lightning-induced surges that
commonly disrupt serial
communications in manufacturing facilities and outdoor
installations.
This high-performance media converter serves various industrial
applications including factory
automation systems, process control networks, and building
management systems where reliable
multi-channel serial communication is essential. The transparent
protocol conversion maintains
data integrity across all supported serial standards without
requiring software configuration or
driver installation, while the flexible channel configuration
allows seamless integration with existing
PLCs, HMIs, and industrial controllers. With its robust design and
comprehensive protection features,
this solution offers industrial operators a reliable and
cost-effective method to extend serial communication
distances while ensuring maximum operational uptime in demanding
industrial environments.
