Overcurrent protection

The PTC-101-S-LC-HV from Moxa is an industrial media converter that converts Ethernet signals in the 10/100BaseT(X) standard via RJ45 connector into fiber optic signals in the 100BaseFX format. It is specifically designed for use in demanding industrial environments, particularly in power distribution systems complying with IEC 61850-3 standards. The device features a robust metallic construction and is designed for operation at extreme temperatures, making it suitable for use in harsh environments. The integrated high-reliability power supply allows direct power from an AC or DC source without an additional transformer, simplifying installation and increasing system reliability.

Applications
This media converter is suitable for industrial networks, particularly in power supply, process automation, and installations requiring high mechanical and electrical durability. Compliance with IEC 61850-3 makes it especially suitable for applications in power supply networks where high immunity to interference and reliability are required. The wide operating temperature range of -40 to 85 °C enables use in outdoor installations, air conditioning systems, production halls, or other environments with significant temperature fluctuations.

Functions and Equipment in Detail
The device features an RJ45 connector for Ethernet connection and a fiber optic port with LC connector for single-mode connections. Automatic MDI/MDI-X detection enables simple cabling without additional crossover cables. The Link Fault Pass-Through (LFPT) function ensures that a fiber optic link failure is also signaled on the Ethernet side, simplifying network diagnostics. Power supply is provided via an input range of 100–240 VAC/VDC (85–264 VAC / 88–300 VDC), enabling flexible integration into existing power supply systems. The integrated power supply offers overcurrent protection to safeguard the device against damage.

Technology Explained Simply
The fiber optic connection operates in single-mode mode at a wavelength of 1310 nm. The optical characteristics are designed to achieve a typical reach of up to 40 km. The transmitter (TX) delivers a power output of 0 to -5 dBm, while the receiver (RX) can receive signals down to -34 dBm. The link budget is 29 dB, ensuring sufficient signal margin for long distances and low signal loss in cabling. The use of single-mode fiber enables high bandwidth and low attenuation, which is necessary for long transmission distances. The metal housing provides additional protection against electromagnetic interference and mechanical impacts.

Compatibility and Accessories
The media converter is compatible with standard Ethernet networks in the 10/100BaseT(X) range and with fiber optic networks in the 100BaseFX standard. The LC connector is designed for single-mode fibers and enables a secure, mechanically stable connection. The devices are designed for mounting on DIN rail, enabling easy integration into existing enclosures. Compliance with IEC 61850-3 and EMC standards EN 55032/35 as well as CISPR 32 ensures immunity to interference and emission characteristics suitable for industrial use.

Mounting and Installation
Mounting is done via DIN rail, enabling quick and secure installation in enclosures. Power supply is provided over a wide voltage range, so no additional conversion devices are required. Cabling is done via standardized RJ45 and LC connectors, with automatic MDI/MDI-X detection simplifying the cabling process. The quick installation guide included in the delivery supports setup.

Operational Advantages
The PTC-101-S-LC-HV offers high reliability due to the integrated high-reliability power supply and robust construction. The wide operating temperature range and high immunity to interference enable use in harsh environments. The LFPT function improves network monitoring, and the long service life (MTBF: 4,660,534 hours according to Telcordia SR332) reduces maintenance and replacement intervals. The use of single-mode fiber enables long transmission distances without signal loss.

Scope of Delivery
The scope of delivery includes the PTC-101 media converter, a quick installation guide, and a warranty card.
