The Moxa PTC-101-M-SC-HV is an industrial media converter that converts Ethernet transmissions over copper cables (10/100BaseT(X)) into fiber optic transmissions (100BaseFX). It is specifically designed for applications requiring high reliability and electromagnetic immunity, such as power substations and industrial automation systems. The device features an integrated power supply and is designed for operation in harsh environments, complying with the IEC 61850-3 standard, which applies to use in substations. The converters are equipped with an SC connector for multi-mode fiber and offer a universal power supply in the range of 100–240 VAC/VDC, making them suitable for various industrial power sources.

Applications

The PTC-101-M-SC-HV is suitable for industrial networks where reliable data transmission over long distances is required, particularly in environments with electromagnetic interference, such as power supply facilities or production halls. Compliance with IEC 61850-3 ensures suitability for use in substations, where high electromagnetic immunity and operational safety are required. The robust construction and wide operating temperature range of -40 to 85 °C enable use in extreme climatic conditions, both indoors and outdoors.

Functions and Equipment in Detail

The device features an RJ45 interface for connection to Ethernet networks and an SC connector for fiber optic connection. The RJ45 interface supports Auto-MDI/MDI-X and Auto-Negotiation, enabling simple and flexible integration into existing networks. The integrated Link Fault Pass-Through (LFPT) function ensures that a failure in the fiber optic connection is also signaled on the Ethernet side, simplifying network monitoring and troubleshooting. A relay output is provided in LV models to signal a power failure; in HV models such as the PTC-101-M-SC-HV, this is not included.

Technology Explained Simply

The optical characteristics of the converter are designed for multi-mode fiber. The wavelength is 1300 nm, the transmit power ranges from -10 to -20 dBm, and the receive sensitivity is -32 dBm. The link budget of 12 dB enables a typical transmission distance of 4 to 5 km. The integrated power supply supports operation with 100–240 VAC/VDC, with current consumption between 200 and 350 mA. The power supply is equipped with overcurrent protection to safeguard the device. The metal housing construction provides mechanical stability and electromagnetic shielding.

Compatibility and Accessories

The converter is designed for use with multi-mode fiber optic cables equipped with SC connectors. The use of single-mode cables is not intended, as the model is specifically designed for multi-mode. The power supply is universal for AC and DC voltages in the range of 100–240 V, enabling flexible integration into various industrial power supply systems. The devices are compatible with networks supporting the 10/100BaseT(X) and 100BaseFX standards.

Mounting and Installation

Mounting is done on a DIN rail, enabling easy installation in enclosures or control cabinets. Dimensions are 152.15 mm (width) × 126.46 mm (height) × 66.65 mm (depth), allowing the device to fit in standardized enclosures. Installation requires no special tools; cabling is done via the RJ45 and SC connectors. The included quick start guide supports setup.

Operational Advantages

The PTC-101-M-SC-HV offers high reliability with an MTBF of 4,660,534 hours according to Telcordia SR332. The robust construction, high electromagnetic immunity, and wide operating temperature range ensure stable operation in demanding environments. The integrated power supply and universal voltage supply reduce the need for additional power sources. The LFPT function improves network monitoring by making fiber optic disturbances visible on the Ethernet side.

Scope of Delivery

The scope of delivery includes the PTC-101-M-SC-HV media converter, a quick start guide, and a warranty card.
