The Moxa PTC-101-S-LC-LV is an industrial media converter that converts Ethernet signals in the 10/100BaseT(X) standard via an RJ45 interface into 100BaseFX fiber optic signals. It is specifically designed for use in harsh environments such as power supply systems, substations, and other industrial facilities that comply with the IEC 61850-3 standard. The device features an LC fiber optic connector and supports single-mode fibers, making it suitable for long transmission distances. The robust construction with a metal housing and DIN rail mounting enables easy integration into existing industrial network infrastructures.

Applications

The converter is designed for use in critical infrastructures where high reliability and stability are required. Compliance with the IEC 61850-3 standard ensures suitability for operation in substations and other electrical installations. The operating temperature range of -40 to +85 °C makes the device suitable for extreme environmental conditions, such as those found in outdoor installations or regions with significant temperature fluctuations. High electromagnetic immunity and environmental tests according to IEC 60068-2-1/-2-14/-2-3, as well as vibration testing according to IEC 60068-2-6, ensure reliable operation under mechanical stress.

Functions and Features in Detail

The PTC-101-S-LC-LV offers redundant power supply, specified for LV models. The input voltage range is 20 to 72 VDC, allowing connection to various industrial power sources. In the event of a power failure, an integrated alarm relay activates a warning function for network monitoring and fault diagnosis. The device supports the Link Fault Pass-Through (LFPT) function, which indicates the status of the Ethernet link in case of fiber optic cable failure, enabling rapid fault detection. The RJ45 interface supports Auto-Negotiation and Auto-MDI/MDI-X, simplifying cabling and enhancing compatibility with various network devices.

Technology Explained Simply

The optical characteristics of the converter are designed for single-mode fibers. Transmission occurs at a wavelength of 1310 nm, with output power (TX) ranging from 0 to -5 dBm. The receiver sensitivity (RX) is -34 dBm, enabling high sensitivity for weak signals. The link budget of 29 dB supports a typical transmission distance of up to 40 km, making it ideal for industrial applications with large distances between devices. The power supply is equipped with overcurrent protection to safeguard the device against damage from current surges. The MTBF (Mean Time Between Failures) is 4,660,534 hours according to Telcordia SR332, indicating high operational reliability over a long period.

Compatibility and Accessories

The converter is equipped with an LC connector for single-mode fibers, making it suitable for applications requiring high transmission distances. Compatibility with 100BaseFX fiber optic and 10/100BaseT(X) Ethernet enables connection between copper and fiber optic networks. Certifications according to EN/UL 62368-1, UL 60950-1, EN 55032/35, FCC Part 15B, and CISPR 32 guarantee safety and EMC compliance. Immunity to electromagnetic interference according to IEC 61000-4-2/-3/-4/-5/-6/-8/-11 ensures reliable operation in electromagnetically noisy environments.

Mounting and Installation

The device is mounted on a DIN rail, enabling quick and secure installation in enclosures. The metal housing provides mechanical protection and good heat dissipation. Dimensions are 152.15 mm (W) × 126.46 mm (H) × 66.65 mm (D), fitting standard enclosure modules. Mounting requires no special tools, and connection cables can be directly connected to the RJ45 and LC interfaces.

Operational Advantages

Operation of the converter is particularly secure due to the redundant power supply and alarm relay. The high operating temperature range of -40 to +85 °C enables use in extreme environments. The integrated LFPT function enhances network monitoring, and the high MTBF reduces maintenance costs. Support for single-mode fibers with a range of up to 40 km makes the device suitable for large-scale industrial networks. Certifications and environmental tests guarantee reliability in critical applications.
