Industrial RS232 RS485 RS422 Fiber Optic Modem Converter 2Mbps 80km DMX512 DIN Rail

Industrial RS232 RS485 RS422 Fiber Optic Modem Converter 2Mbps 80km DMX512 DIN Rail

Model: LNK-IRS93 series

 Product Description & Overview

The Industrial Serial RS232/RS485/RS422 Fiber Optic Modem delivers robust protocol

conversion for mission-critical serial communications in harsh environments. This industrial-

grade media converter seamlessly transforms standard RS232, RS485, and RS422 electrical

signals into optical fiber transmissions, effectively extending serial communication distances

up to 2km over multimode fiber and 80km using single-mode fiber optic cables. The implementation

of fiber optic technology completely eliminates common industrial communication challenges

including electromagnetic interference, ground loop issues, and lightning-induced damage

that typically plague traditional copper-based serial connections.

Engineered specifically for industrial automation applications, this fiber modem significantly

enhances data communication reliability through its advanced optical isolation technology

that provides complete electrical separation between connected devices. The hardened

metal housing and wide operating temperature range ensure stable performance in

demanding conditions encountered in factory automation, process control systems, and

outdoor industrial installations. The device supports full-duplex communication for RS422

and RS232 protocols while maintaining robust multi-drop network capability for RS485

networks, making it suitable for both point-to-point and multi-point serial communication

topologies.

This versatile fiber optic modem finds ideal application across numerous industrial sectors

including PLC and DCS system integration, SCADA network expansion, building automation

control, and transportation signal management systems. Its plug-and-play installation requires

no configuration changes to existing serial equipment, while the transparent protocol conversion

maintains complete data integrity without packet loss or latency issues. The solution provides

industrial operators with a secure, interference-free serial communication alternative that

dramatically improves network reliability while reducing maintenance costs associated with

traditional copper serial cable installations in electrically noisy environments.
