TURCK Unveils Motor Starter Economy Modules

TURCK has developed the BL20 motor starter economy module, which uses Swire technology to provide a daisy-chain connection from a single I/O slice to each motor starter via a ribbon cable. 'Swire technology provides plug-and-play connection, eliminating the labour required to hardwire motor starters to digital output points and auxiliary contacts back to digital inputs. 'By using this connection technology, it is now possible to control up to 48 motor starters on a single fieldbus node,' said Nick Clute, product specialist with TURCK's network and interface division.

TURCK BL20 Motor Starter Module allows three-phase motor control to be connected to the same rack as standard I/O. In addition, with the Swire connection, motor starters can be mounted on separate DIN-rails within the same panel - pairing the flexibility of standard motor starters with the advantages of fieldbus control. 'When motor starters are on a fieldbus, the benefit is that they can be located close to the motor they are controlling,' Clute added.

The BL20 motor starter module is available in sizes ranging from .08 to 20hp, direct and reversing, for use on Devicenet, Profibus, CANopen, Ethernet/IP and Modbus TCP/IP networks with both standard and programmable gateways. Trip indication may also be added to any motor starter. The BL20 motor starter module complies with industrial switchgears standards IEC/EN 60947-4-1 and carries an IP20 environmental protection rating. It consists of a gateway, base modules and electronic modules.

I/O modules are configured independently from the Fieldbus protocol, and up to 72 I/O modules may be connected to a gateway, allowing systems including up to 1,152 digital I/O points or 288 analogue channels. All BL20 gateways are compatible with Turck's I/Oassistant software package, developed to perform initial configuration, parameter setup, documentation, commissioning and diagnostic functions for on/offline usage. I/Oassistant verifies that all power and size restrictions are met.

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.
