Cost effective Ethernet switches provide storm protection for industrial users
Available from Switchtec, Kyland’s Opal series of industrial Ethernet switches meet the growing demand for smaller, smarter control panels that need to communicate with external devices and systems in the industrial environment
A
vailable in 5, 8, and 16 port variants, the versatile Ethernet switches are
unmanaged types, and as such require no setting up, they are ‘plug & play’. An unmanaged switch allows Ethernet devices to communicate with each other automatically using auto-negotiation to determine parameters such as data rates and whether to use half-duplex or full- duplex mode. Kyland’s Opal series Ethernet switches
are supplied with dual/redundant power inputs, and being multi voltage they are able to work on 18 to 30VAC, and 12 to 48VDC powered systems. The switches are DIN rail mountable and are of a compact design, the smallest OPAL 5 measuring just 115 x 68 x 30mm in size. Supplied in a rugged aluminium DIN rail mount housing the switches are rated to IP30 and have an operating temperature range of -10 to +60°C. For ease of use in deployment, the switches feature full LED Link/ACT indication and dual LED power supply indication. Kyland’s Opal series Ethernet switches feature selectable storm protection. A broadcast storm occurs when a network
system is overwhelmed by continuous multicast or broadcast traffic. When different nodes are sending/broadcasting data over a network link and the other network devices are rebroadcasting the data back to the network link in response, this eventually causes the whole network to go into meltdown and the failure of network communication. So being fitted with selectable storm protection, the Ethernet switches protect the network from this potentially dangerous problem. The Opal series is manufactured in
accordance with FCC CFR47 part 15 and EN55022/CISPR22 Class A for EMI, and IEC61000-4-2/3/4/5/6 and IEC60068- 2/27/32 for EMS. Providing confidence for the specifier or buyer, the all- important approvals are cULus, UL508 class1 Div 2, Atex zone 2 IECEx, FCC and CE approved. Further, each Kyland Opal Ethernet switch is supplied with a five year manufacturer’s warranty. For use in control panel systems for
building management systems (BMS) integration, the switches will find favour with panel builders, equipment manufacturers, OEMs and those directly
The switches are DIN rail mountable and are of a compact design
involved with BMS integration. They are a cost-effective product providing a compact, easy to install and set up solution that is fully approved and manufactured to internationally recognised standards.

FLEXIBLE CONDUIT SPECIFICATION GUIDE FOR HAZARDOUS AREAS R
esponding to the demand to safely protect power and data
cabling in today’s interconnected world, Flexicon has launched its ‘Products and Solutions Guide for Hazardous Areas.’ Tim Creedon, sales & marketing
director for Flexicon, says: “Failure to protect power and or data cabling in areas with the potential risk of explosion can be catastrophic for
safety and operational efficiency. “It has never been more
important to specify cable protection correctly to ensure on- going operation throughout a system’s life and protect people, property and processes. Hazardous areas, by their nature, present many risks and depending on the application the hazards faced can vary. The risk of explosion due to
flammable liquids, gases or dust, hazards such as the ingress of water, corrosion, exposure to chemicals, impact, crushing, fire, UV light and vandalism can all impact. “Our new specification guide
features 16 different cable protection solutions for use in hazardous areas. The guide makes it easy to specify a system of both conduit and gland or fitting to provide the right level of protection.” The 46-page guide highlights

many of the potential hazards faced by cabling, using simple icons. It is focused on product solutions for hazardous areas and features Flexicon’s range of flameproof barrier glands with the latest IECEx, ATEX and CU-TR certification. It
also features conduits for hygienic applications and Flexicon’s new stainless steel annular corrugated conduit systems, FSS and FSSBRD. With an easy-to-use selection
table, specifiers and engineers can quickly compare the performance properties of the sixteen different conduit systems and the variety of glands and fittings. “It is not enough to select the correct flexible conduit; installers also have to match it to the right fitting according to the application. It is often the conduit-to-fitting and fitting-to-equipment interfaces that are crucial for protection and this guide offers an effective tool to aid this specification process.”
