Industrial Multi-Channel RS-232/422/485 Serial to Fiber Converters

Industrial Multi-Channel Serial to Fiber Converters Overview

The E-link LNK-IRS Series is an industrial-grade multi-channel RS232/RS485/RS422 to fiber optic converter, designed to extend serial communication up to 2km over multimode fiber or 20km over single-mode fiber.

It supports 4 to 16 channels of RS232 or RS485, and 2 to 8 channels of RS422, with flexible mixed-signal configurations such as 8CH RS232 + 8CH RS485 or 8CH RS485 + 4CH RS422.

Featuring a DIN-rail mount design, it ensures easy installation in harsh industrial environments. Optical fiber transmission eliminates EMI, ground loop, and lightning interference, ensuring high data reliability, security, and performance.

Ideal for industrial automation, process control, stage lighting, and traffic management systems.
