Phoenix Contact 2708397

The PSI-MOS-RS422/FO 850 T serves as a FO converter designed for industrial applications, featuring integrated optical diagnostics and an alarm contact. It supports RS-422/RS-485 4-wire/INTERBUS protocols with a maximum data transmission rate of 2 Mbps.

This device is equipped with two FO interfaces (BFOC) operating at a wavelength of 850 nm, suitable for both PCF and fiberglass cables (multimode). The operational temperature range spans from -20 °C to 60 °C, while storage conditions allow temperatures from -40 °C to 85 °C. The unit's degree of protection is rated at IP20.

With a typical current consumption of 120 mA at a nominal supply voltage of 24 V DC, it offers a maximum power dissipation of 2.88 W. The device is designed for a maximum switching voltage of 60 V DC and a limiting continuous current of 0.46 A. The relay output functions as an alarm output with a single channel for monitoring.

For connection, it utilizes a pluggable screw mechanism, ensuring secure assembly with a tightening torque of 0.56 Nm to 0.79 Nm. The converter also provides a range of features, including a maximum transmission length of 2800 m with a 3 dB system reserve, ensuring effective communication over extended distances.

Compliance with electromagnetic compatibility standards (2014/30/EU) and various certifications confirms its suitability in industrial environments. Special installation instructions should be adhered to as provided in the documentation.
