Pneumatic Timers are Small and Lightweight

TME has introduced a range of pneumatic time relays from Crouzet, with time ranges of 0.1 to 30 seconds and NO or NC outputs, in which voltage is replaced with pneumatic pressure/technical air. Time value setting is done by an embedded potentiometer that ensures an accuracy of +/-5 per cent. Models available include the Crouzet 81503540, with positive NC output and the time of 0.4sec; Crouzet 81506540, with negative NO output and the time of 04sec; Crouzet 81503710, with positive NC output and the time of 0.1 to 15sec; Crouzet 81506710, with negative NO output and the time of 0.1 to 15s; Crouzet 81503720, with positive NC output and the time of 0.1-30sec; and Crouzet 81506720, with negative NO output and the time of 0.1 to 30s.

The two first models have fixed time ranges without the possibility of adjustment, while the other models allow adjustment of time delay within the given ranges. Each model features nominal working pressure of 2-8 bar; 170Nl/min flow at 6 bar pressure; minimum reset time of less than 0.1sec; nominal operation temperature of 5 to 50C; mechanical durability for around 10 million cycles; and M4 process connection. Small sizes, small weight and high mechanical durability make this equipment suitable for use in the majority of complex pneumatic systems and everywhere where pneumatic time delay is necessary.

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.
