ETHERNET SWITCH SIMPLIFIES MIGRATION TO FIBRE OPTIC NETWORKS

S iemens is expanding its Rug- gedcom portfolio with a new Ethernet 19 inch rack switch. The Ruggedcom RST2228 is a rugged Layer 2 rack switch with four integrated 1/10 Gbit/s uplinks and up to 24 field modular 10/100/1000 Mbit/s inter- faces supporting IEEE 1588 Transpar- ent Clock. Its high port density helps significantly reduce capital expenses by reducing the number of network devices needed. The combination of precision timing and network communication on a single network eliminates mainte-

pre-configured with modules installed, but also allows for quick in-field set-up and modifications with the separately orderable media modules Ruggedcom RMM2973-4RJ45, RMM2973-4FC and RMM2972-4SFP. This enables simpli- fied migration from copper to fibre optic networks – one of the major challenges of digitalisation. Further savings can be found by purchasing only the necessary modules for the RST2228 to meet im- mediate needs.

nance costs related to timing solutions that require dedicated wiring. The device is rugged rated and features an operat- ing temperature from -40 to +85 °C, as well as electromagnetic interference im- munity. The product can be used in the harsh environments of electric power, transportation and oil and gas indus- tries, and is ideal to handle ever growing amounts of data. The 24 10/100/1000 Mbit/s interfac- es are field modular based on six mod- ule slots, each of which can support four interfaces. The product can be ordered

NEW VOLTAGE VERSIONS FOR POWER SUPPLY

THE new voltage versions of the Trio Power power supply range from Phoenix Contact provide a reliable supply for loads, even under harsh ambient condi- tions. The power supplies each include two 12 and 48 V devices with 5 and 10 A output current that are particularly well-suited for applications in telecom- munications and machine building. Like their prede- cessors, they are electrically and mechanically robust. The power supplies feature dynamic boost, which starts even heavy loads with 150 percent of the nominal current for five seconds. The robust design, with its high shock and vibration resistance, its high electric strength, high MTBF values of over 1 million hours, along with active function monitoring with dc OK LED and floating relay contact, ensures that all connected loads are reliably supplied. Tool-free wir- ing with Push-in connection saves time during in- stallation. The slim 35 to 68 mm wide design saves space in the control cabinet. The extensive tempera- ture range of -25°C to +70°C guarantees a high level of flexibility in terms of deployment. DM285: THERMAL IMAGING DIGITAL MULTIMETER T he FLIR DM285 thermal imaging digital multi- meter is an industrial inspection, troubleshoot- ing and diagnostic tool, suitable for a variety of electrical and electro-mechanical applications, as well as for heating, ventilation, air conditioning, and refrigeration (HVAC/R) inspection. Electrical professionals and field service profes- sionals can use the DM285 for non-contact thermal imaging to scan for overheating system components, and then use its test functions to troubleshoot and diagnose the fault. The DM285 is ideal for trouble- shooting electrical applications, including overheat- ing panels, fuses, and loose connections. It can be used for diagnosing issues in electro-mechanical equipment such as rotating and reciprocating pumps and compressors, electric motors and drives, and as- sociated monitoring and automation systems. It is also a good choice for HVAC/R applications, as well as repair of printed circuit board components, voltage regulators, power supplies and microprocessors. Enquiries: +27 (0)11 801 8200
