Compact Time Converter for reliable operation in harsh environments

  • Compact Ruggedcom RMC8388 for time conversion between IEEE 1588v2 and IRIG-B
  • Cost effective device for the Electric Power Market
  • Usage of legacy IEDs (Intelligent Electronic Devices) within advanced Ethernet

Siemens has expanded its portfolio of rugged network components with the Ruggedcom RMC8388 - a cost effective compact time converter designed to operate in harsh environments with widely varying climatic and environmental conditions. Withstanding extreme temperature from -40 up to +85 degrees Celsius, vibration and shock the device offers high reliability for Electric Power applications. By enabling cost effective time synchronization Ruggedcom RMC8388 reduces both capital expenditures and maintenance costs.

The Ruggedcom RMC8388 is available in multiple variants and can convert between the modern Precision Time Protocol IEEE 1588v2 and the legacy IRIG-B (Inter-range instrumentation group) time codes or PPS (pulse per second). The RMC8388 enables the usage of legacy IEDs (Intelligent Electronic Devices) within modern Ethernet networks without the need for maintaining a separate network for time synchronization.

The compact form factor makes the Ruggedcom RMC8388 ideal within modern Ethernet based networks while it uses only limited additional space in existing cabinets and defers capital expenditures by enabling cost effective time sync to existing non IEEE 1588 capable IEDs. Besides extending the service life of legacy IEDs, the new Ruggedcom RMC8388 also enables the connection of legacy time sources to a modern Ethernet based network to enable upgrading in phases without the need for upgrading everything at once.

Ruggedcom RMC8388 also reduces high maintenance costs on legacy coax cabling by replacing them with standard Ethernet cabling for both communications and timing purposes, all the way to the switchyard cabinets.

Im Focus: Novel light sources made of 2D materials

Physicists from the University of Würzburg have designed a light source that emits photon pairs. Two-photon sources are particularly well suited for tap-proof data encryption. The experiment's key ingredients: a semiconductor crystal and some sticky tape.

So-called monolayers are at the heart of the research activities. These "super materials" (as the prestigious science magazine "Nature" puts it) have been...

Im Focus: Etching Microstructures with Lasers

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.

This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Im Focus: Light-driven atomic rotations excite magnetic waves

Terahertz excitation of selected crystal vibrations leads to an effective magnetic field that drives coherent spin motion

Controlling functional properties by light is one of the grand goals in modern condensed matter physics and materials science. A new study now demonstrates how...

Im Focus: New 3-D wiring technique brings scalable quantum computers closer to reality

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.

"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...

Im Focus: Scientists develop a semiconductor nanocomposite material that moves in response to light

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
