    Industrial Multi-Channel RS232/422/485 Fiber Converter 2Km–20Km

    Industrial Multi-Channel RS232/422/485 Fiber Converter 2Km–20Km

    Overview

    The LNK-IRS Series delivers high-performance multi-channel serial-to-fiber conversion designed for

    mission-critical industrial environments. Supporting up to 16 serial ports with flexible combinations of

    RS232, RS485, and RS422, it provides secure and interference-free data transmission over fiber links

    up to 20Km. With rugged aluminum housing, wide temperature tolerance, and fanless DIN-rail design,

    it ensures long-term stability in automation, traffic, and stage lighting control systems.

    Features

    • Flexible Port Options: Supports 4–16 RS232, 4–16 RS485, or 2–8 RS422 channels.

    • Configurable Mix: Custom combinations such as 8 RS232 + 8 RS485 or mixed RS232/RS422.

    • Reliable Fiber Extension: MMF up to 2Km, SMF up to 20Km with SC/ST/FC/SFP connectors.

    • Industrial Build: IP40 aluminum case, fanless cooling, DIN-rail mounting.

    • Rugged Protection: Reverse polarity, 15KV ESD, and surge immunity.

    • Wide Temp Range: Operates reliably from -40°C to +80°C.

    • Visual Monitoring: Power, fiber link, and channel activity LED indicators.

    • Long Service Life: MTBF over 216,000 hours, backed by 5-year warranty.
