Phoenix Contact PSIMOSRS485W2FO850E RS485 to Fiber Converter
The PHOENIX CONTACT PSI-MOS-RS485W2/FO 850 E is a robust fiber optic converter specifically engineered for RS-485 2-wire bus systems like SUCONET K and Modbus. It combines RS-485 communication with fiber optic transmission, enabling long-distance data transfer with high reliability. Key features include integrated optical diagnostics for continuous monitoring, a floating switch contact for alarm generation, and high-quality electrical isolation between interfaces and power supplies. This converter is approved for use in zone 2 and features an intrinsically safe fiber optic interface, making it suitable for applications in hazardous environments. It supports data rates up to 500 kbps and can be modularly combined with PSI copper repeaters.
