USB DrDAQ Device for Teachers and Technicians

Saelig has introduced the USB DrDAQ, a combination scope/data-logger/IO board that offers a collection of 15 I/O channel in a compact, low-cost device designed for hobbyists, teachers and technicians. Software provided with the unit provides an easy-to-use 100kHz-bandwidth oscilloscope and datalogger, with extra input and output capabilities straight out of the box.

Built into the USB DrDAQ are a microphone, light sensor, RGB LED, oscilloscope and resistance inputs, four digital I/O ports, three sensor ports, a pH/redox sensor input and a signal generator output. The unit is powered from the USB port so there is no need for an external power supply. USB DrDAQ samples at 1MSa/s and can be used as a single-channel 8-bit 100kHz oscilloscope or spectrum analyser with the ability to measure voltages up to +/-10V.

The device's 10-bit D/A output features a 10-bit signal generator - a standard function generator, but also an arbitrary waveform generator (AWG) - so customised waveforms can be created. An RGB LED can be used to display any colour for a variety of indicator purposes. Two of the I/O ports can be used as pulse counting inputs, or PWM (pulse-width modulation) outputs. The sensor ports can be used with a range of temperature, humidity and oxygen sensors, or with custom sensors built by the user.

USB DrDAQ will find its way into a variety of applications from education to research for signals at audio frequencies and beyond. It is supplied with a free Windows Software Development Kit (SDK) with fully documented function calls to control all aspects of the device, so it can even be integrated into other programs in C, C++, Microsoft Excel and National Instruments Labview.

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...

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...

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.
