USB DAP for High-Speed Simultaneous Sampling 16-Bit Resolution – 8 Channels – 8 Msamples/sec – 1 GB Memory

High-performance, PC-based data acquisition applications have a new option: xDAP 7400 from Microstar Laboratories, a leader in data acquisition products with distributed intelligence for PC systems. xDAP 7400 features an embedded 1.8GHz Intel processor and runs DAPL 3000, a major new release of DAPL, the real-time operating system that runs on every Data Acquisition Processor (DAP) system. Distributed intelligence like this lets you run timing-critical processes in real time, even with PC-based data acquisition under Windows. The local PC that controls xDAP 7400 connects to it through the front-panel USB 2.0 connector. That PC also can provide xDAP 7400 data acquisition services to other PCs over network connections.

A Semi-Autonomous Data Acquisition System

xDAP 7400 is a semi-autonomous data acquisition system: it can – after programming – run independently from its host PC. PC software communicates with, configures, and controls the system, but xDAP 7400 can be set up to run for long periods – or even indefinitely – without any connection to a PC. With an application using a software trigger, described below, data can be selected for processing automatically, and the host PC can be disconnected. While operating independently, xDAP 7400 can extract and process only what you care about from a sampled data stream. It lets you improve your signal quality by running the data stream through digital filters before storing it in local memory for transfer to the PC when the PC is connected and ready to accept the transfer. The distributed intelligence of multiple xDAP 7400s allows capture, buffering, and reduction of data, for faster transfer of information through limited PC host capacity.

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.
