Amplicon Offers Ethernet Extender Units

Ethernet extenders use DSL (Digital Subscriber Line) to extend Ethernet links up to 10km over a single pair of low-grade copper wires. The units operate transparently as part of an existing network, without requiring driver installation or complex setup procedures. All 'IP' traffic that could be sent across a standard patch cable can be sent across an Ethernet Extender link.

The potential to save money using Ethernet Extenders becomes apparent when they are used instead of a fibre-optic link or a wireless bridge. An old pair of telephone wires or defunct RS485 cabling from a security camera can suddenly become a precious commodity on a site that requires long-range Ethernet connections. Even in simple applications where a run of Cat5 cable exceeds the 100m distance limit for Ethernet, Ethernet Extenders can be deployed to save the cost of signal repeaters, power supplies and associated housings for the equipment.

One of the main early adopters of this technology was the building-controls sector. BMS system controllers were traditionally connected together using RS485 cabling to provide slow but reliable site-wide communication. With the transition to Ethernet-based controllers and general convergence on IP-based systems in industry, many system integrators found themselves having to re-install a communication network based on CAT5(E) cabling to support high-speed Ethernet links. By using Ethernet Extenders, existing RS485 cables can be used.

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin

7/8 16UN Connectors that Provide 600 Volts and 15 Amps

TURCK announces new A-Size 3 and 4-pin 7/8 16UN powerfast™ connectors that provide up to 600 Volts and 15 Amps of power. These IP67 rated connectors provide a modular wiring system designed to handle high current applications for machine power distribution, while providing resistance to vibration commonly associated with conveyors, motors and material handling applications. The cordsets are available with a tray rated, exposed run PVC flexlife ® cable, with or without STOOW rating, and 14 AWG wires that allow you to replace hard wiring with a robust, quick disconnect system that saves the time and money spent installing a conduit system. The A-Size powerfast line offers male and female, straight connectors, standard and custom lengths, and pigtails or extensions. To make the system complete, fully encapsulated mating receptacles, with 1/2”-14 NPT mounting threads are available.
