Industrial Multi-Channel RS232 RS485 RS422 Fiber Converter 16 Ports DIN Rail 20km
Model: LNK-IRS series
Product Description & Overview
The Industrial Multi-Channel RS-232/422/485 Serial to Fiber Converters represent a high-density
solution for industrial communication networks requiring multiple serial port conversion. These
robust media converters efficiently transform 4 to 16 channels of RS232, RS485, or RS422
electrical signals into optical fiber transmissions, extending communication distances up to 2
kilometers using multimode fiber and 20 kilometers over single-mode fiber infrastructure. The
platform offers exceptional configuration flexibility, supporting various channel combinations
including mixed interface arrangements such as 8 RS232 + 8 RS485, 8 RS232 + 4 RS422,
or 8 RS485 + 4 RS422 ports within a single compact unit.
Engineered specifically for demanding industrial environments, these multi-channel converters
implement complete electrical isolation through fiber optic technology, effectively eliminating
electromagnetic interference, ground loop problems, and lightning surge damage that commonly
affect traditional copper-based serial networks. The DIN-rail optimized design ensures straightforward
installation and maintenance in control panels and industrial cabinets, while the hardened construction
withstands extreme operating conditions encountered in factory automation, process control facilities,
and outdoor industrial installations.
These high-port-density converters find ideal application across numerous industrial sectors including
factory automation systems, process control networks, SCADA monitoring infrastructure, and building
management systems. The transparent protocol conversion maintains complete data integrity across
all channels without requiring configuration changes to existing serial equipment, while the modular
architecture allows for easy system expansion as communication needs evolve. This solution provides
industrial operators with a reliable, interference-resistant serial communication platform that significantly
enhances network reliability while reducing cabling complexity and maintenance costs associated with
traditional multi-port serial communication installations in electrically challenging environments, making
it particularly suitable for transportation management systems, energy distribution networks, and industrial
IoT applications requiring secure multi-channel data transmission.
