Controllers Enable High-Temperature Processing

National Instruments has released two Compact RIO programmable automation controllers (PACs). These are said to offer engineers and machine builders an ideal solution for high-performance measurement and control applications operating at extended temperatures. The NI cRIO-9023 and NI cRIO-9025 real-time controllers are also available with conformal coating for additional protection of components and circuitry within harsh conditions.

The Compact RIO controllers provide even more processing for advanced measurement and control applications ranging in temperatures between -40 and 70C. The NI cRIO-9023 controller has a 533MHz Power PC processor and the NI cRIO-9025 controller has an 800MHz Power PC processor, as well as dual Ethernet ports for network programming, communication and expansion I/O.

Both controllers work with the existing Compact RIO reconfigurable chassis, which include field-programmable gate arrays (FPGAs) that are programmed using the NI Labview 2009 graphical system design platform.

Using Labview and Compact RIO, engineers can quickly implement custom analogue and digital control loops, along with high-speed signal-processing algorithms to meet their advanced measurement application needs. In addition to an extended operating temperature, the Compact RIO controllers are available with conformal coating.

This coating is a specially formulated thin film material applied directly to circuit boards or circuit card assemblies and provides an impermeable seal to protect circuitry from humidity, moisture, mould, mildew, fungus, dust and corrosion caused by exposure to extreme environments. Application areas in which conformal coating can provide protection include marine, railway, automotive, factory monitoring, fuel-cell testing and oil and gas refining.

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.
