Product Description

The NS485I4 Modbus Converter is an industrial-grade RS485 Fiber Interface Module designed to enable robust communication in harsh environments. It integrates dual RS485 ports and a single fiber optic interface, supporting seamless conversion between electrical RS485 signals and optical data transmission. Compatible with Modbus RTU/TCP protocols, this converter operates within a wide voltage range of 9-36V DC and withstands temperatures from -40°C to 85°C, making it ideal for automation, energy management, and SCADA systems. Its Industrial Fiber Optic Modbus capability ensures immunity to EMI/RFI interference, while enabling long-distance communication up to 20km via fiber optics. Key advantages include hot-swappable terminals, DIN-rail mounting, and plug-and-play configuration, though it requires fiber optic expertise for initial setup. The module supports daisy-chaining for multi-device networks without additional repeaters.
