Ethernet Switches Supplied For LNG Terminal

Garrettcom's Ethernet switches are providing a redundant network infrastructure for a floating LNG storage and regasification terminal off the coast of Italy. Garrettcom supplied 6K32TRC (managed) and ES42H-2SC (unmanaged switches), all configured for 24V DC power. The 6K32TRC is a 32-port, free-convection-cooled rack-mount Ethernet switch that has been designed for applications where rack space is at a premium or where strict EMI/EMC regulations preclude the use of conventional fan cooling.

It uses an innovative casework design and thermal-management techniques to guarantee operating safety in hazardous environments. The 6K32TRC managed switch provides 16 fixed 10/100Mb copper ports, plus two modular slots that can be freely configured to best meet user requirements. The modular slots can accommodate a mixture of 10/100Mb copper ports, 100Mb fibre ports and Gigabit ports. For example, users can specify up to a further 16 10/100Mb copper ports to give 32 in all, or between one and four Gigabit ports, mixing and matching as required.

Gigabit ports can be configured for a variety of fibre and copper cabling types and distances. The ES42H is a compact, hardened and rugged-edge switch that provides a total of six Ethernet ports. Four are always RJ-45 copper ports and the remaining two can be user specified as two 100Mb fibre ports, or one fibre and one copper port, or two copper ports. The ability to connect these edge switches in either 'star' or 'ring' configuration using non-proprietary self-healing protocols such as RSTP-2004 was said to be one of the benefits of the Garrettcom products in this application.

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.
