Description
The Perle PSI-MOS-RS422/FO1300 E Serial to Fiber Converter (Part No. 27085754) provides a reliable and cost-effective way to extend serial communication over long distances using fiber optic cabling. Supporting RS422/485 4-wire connections, this converter transparently bridges RS232, RS422, and RS485 devices to duplex SC fiber.
Designed for industrial and commercial environments, it enables data transmission over multimode fiber up to 27 km (16.7 miles) and single-mode fiber up to 45 km (28 miles). The unit includes a 24VDC wall power adapter, ensuring easy installation and dependable operation. By transmitting serial data over optical fiber, users benefit from enhanced immunity to electromagnetic interference and extended reach compared to traditional copper cabling.
