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.
