Wireless Mesh Gets IP-Based Networks Capability

Virtual Extension has announced the compatibility of Diversity Path Mesh to the IP networks environment. Users of the company's VEmesh products can now benefit from both the TCP/IP protocol for back office and the Diversity Path Mesh de-facto standard for high-performance Mesh Wireless Networks for the communication with the smart meters or networks. The TCP/IP compatibility is offered as an option in the Gateways of VEmesh networks, the other elements of the wireless network being standard VEmesh nodes.

VEmesh Gateways with the TCP/IP interface have an RJ45 connector fit to standard Ethernet networks. With the addition of the TCP/IP interface option, Virtual Extension offers smart meter and sensor manufacturers and system integrators a rich set of standard interfaces, which also includes Modbus, USB, UART and RS485. VEmesh has been built to provide OEMs with license-free RF communications in difficult environments and over long distances.

Virtual Extension's Diversity Path Mesh synchronised flooding technology is said to ensure that each transmission is optimally relayed by the nodes surrounding it. Instead of investing in computing and network resources to select the best radio path and then instruct specific nodes, the network benefits from the space diversity of a multitude of propagation paths, eliminating the need to route and manage and increasing the robustness and range of the network. VEmesh is sold in chip, customised module and standard module formats.

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.
