CFRS
RS485 to Optical Fiber (ST) Signal Converter
RS485 serial to fiber optic communication converter with ST connection for integrating devices into supervisory networks.
Description
The CFRS is a converter designed to integrate industrial communication networks by converting signals from optical fiber to RS-485. This device is essential for applications requiring long-distance, high-speed data transmission and immunity to electromagnetic interference.
Used in automation, control and monitoring systems, the CFRS enables secure interconnection of RS-485 devices in industrial environments and other sensitive applications. It supports all communication protocols based on RS485 (ANSI/TIA/EIA-485-A, two-wire) and optical fiber, making the network fully immune to electrical noise, electromagnetic induction, lightning and voltage surges, increasing data traffic reliability, communication speed and the distances between IEDs and the data server or supervisory control system (Scada).
The CFRS is built to strict quality standards and uses state-of-the-art electronic components (SMD). Its hardware is designed to withstand harsh operating conditions and can be installed directly in power substation panels. It meets the requirements for performance, withstand capability and reliability specified by IEC, DIN, IEEE and ABNT standards.
