Industrial 4 Channel RS232 RS485 RS422 Fiber Media Converter 20km DIN Rail

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.
