Backplane Tackles Bandwidth-Intensive Applications

Kontron has unveiled a 4U backplane for PICMG 1.3-based system designs, suitable for medical, digital signage, gaming, infotainment, surveillance and industrial engineering applications. The new xPB-13E9P3 backplane offers PCI and PCI Express (PCIe) Gen 2 support for full-height 4U systems. With 32 PCIe lanes, the PICMG 1.3-compliant backplane tackles bandwidth-intensive applications with its cost-effective and densely packed design for use with standard PCIe and PCI extension cards.

In order to support any standard PCIe extension card, an integrated non-blocking switch doubles the 16 PCIe lanes from the system host board (SHB) to the four PCIe x4 Gen 2 slots and the PEG slot on the backplane. The switch is configurable via software, allowing each of the x4 slots to be individually populated with x1, x2 or x4 input/output (I/O) cards. The PCIe bandwidth can also be routed directly to dedicated ports without disturbing the CPU board. The three PCI slots of the Kontron xPB-13E9P3 allow original equipment manufacturers to leverage existing PCI extension cards.

The xPB-13E9P3 backplane provides a cost-efficient solution for applications with extreme bandwidth requirements. The full-size backplane is designed for high-throughput use (5.0GT/s per PCIe lane) with the latest frame grabbers, graphics and network cards. The PICMG 1.3 backplane also provides ample resources for applications where multiple video cards are required, such as in test and measurement, digital mock-up and simulation. This makes the new backplane a suitable host for a GPGPU system for cost-efficient, high-performance embedded computing tasks (HPECs).

All these applications benefit from the PICMG 1.3 specification, which combines the cost efficiency of a motherboard-based solution with the high bandwidth of a complex and densely packed serial switched backplane system design, according to the company. The Kontron xPB-13E9P3 offers one PEG (PCIe x16), four PCIe x4 and four PCIe x1 as well as the PICMG 1.3 slot for the SHB. Connections for four USB 2.0 ports, two SATA ports and one LAN port round out the interface offerings of the PICMG 1.3 backplane.

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.
