Emerson Unveils Foundation Fieldbus Interfaces

Emerson Process Management has introduced Foundation Fieldbus interfaces for Controlwave RTUs and ROC800-series remote operations controllers. The Foundation Fieldbus interface is said to combine the benefits of Foundation Fieldbus with proven RTUs to reduce costs and increase efficiency in a range of oil and gas, water and wastewater applications.

It extends the power of Plantweb digital architecture beyond traditional plant walls, where environmental demands on power consumption, temperature range, physical size, and mounting footprint are important system design considerations. Operational performance is improved through the increased accuracy of digitally retrieved process data and diagnostic information provided to decision makers. Integrating the RTU and remote operations controllers into Plantweb architecture is said to provide enterprise-wide optimisation, instrument diagnostics, predictive maintenance scheduling, calibration, and reconfiguration.

The Foundation Fieldbus interface allows Controlwave and ROC800-series controllers to access multiple variables over a single pair of wires in a point-to-point or multi-drop configuration. The interface eliminates the need for technicians to cover hundreds of kilometres to configure and diagnose instrument problems in wide-area Scada networks. Installation and wiring costs are also reduced as centralising with fieldbus eliminates the need for extra hardware.

A Field Interface Configurator is said to make set-up and commissioning easier and faster. This software tool schedules, commissions, and creates data relationships between fieldbus devices and variables within the Controlwave or ROC800-series controller. The configurator is the only software tool needed to commission and deploy the Foundation Fieldbus interface.

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.
