UEI Launches High-Resolution Analogue Input Boards

United Electronic Industries (UEI) has released the DNA- and DNR-AI-217 high-speed, high-resolution analogue input boards. The boards provide 16 fully differential channels of 24-bit, +/- 10V (gain=1) analogue input and one single-ended dedicated channel for thermocouple cold junction compensation. This configuration is said to eliminate the noise and offset errors associated with multiplexed inputs and, at the same time, allows all 16 channels to be sampled simultaneously.

In addition, seven software-selectable gains accommodate a range of input signals. Both boards offer 30kS/s sampling rates per channel and 480kS/s aggregate for an entire board. The DNA version of the board is designed for mounting in any of UEI's six-slot PowerDNA, UEIPAC, UEISIM and UEIModbus 'Cubes'.

The DNR version is designed for use with the six- or 12-slot rack-mounted Halfrack and Racktangle chassis. Software for the DNA/DNR-AI-217 is provided in the UEIDAQ framework. The framework provides an easy-to-use API that supports programming and operating systems such as Windows, Vista, Linux and most real-time operating systems, for example QNX, RTX and RT Linux. In addition, the board is fully supported by Labview, Matlab/Simulink, Dasylab or any application supporting ActiveX, OPC or Modbus TCP control.

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.
