DKD Ethernet Modules Control Robotic Tool Changers

Robotic tooling manufacturer ATI Industrial Automation has introduced DKD Ethernet modules that control and communicate with the company's heavy automatic robotic tool changers. The modules utilise Ethernet/IP while passing Devicenet network and power to the tool-side. This provides for utilisation of Ethernet/IP on the robot up to the tool changer and short connection times to the tool-side equipment by using Devicenet Quick Connect equipment on the tooling.

The modules also feature ATI's patent-pending arc prevention circuit, which protects all electrical power contacts against reduced life that can be caused by loads with high inrush current during coupling/uncoupling. Provided through a connector on the tool module, ATI's Tool Stand Interlock technology prevents uncoupling of the tooling when not safely nested in the tool stand. DKD Ethernet module features: integrated Ethernet/IP interface; Devicenet pass-though with standard five-pin mini connector; arc prevention circuit on all electrical power contacts; two auxiliary power pass-throughs, TSI to safely uncouple the tooling; Tool-ID, adjustable from 0 to 9; integrated web server for tool changer configuration and status, internal pin block for valve electrical connections.

The module's multi-function design requires fewer cables and connectors and allows for a compact assembly. The modules have an anodised aluminium housing, precious metal-pated spring and contact pins and nitrile seals to ensure reliability. Their electrical rating is 24V DC for control signals and 5A/24V DC for pass-through signals.

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.
