Multi-Pair Foundation Fieldbus M-EZ Cables Offered

Northwire has increased its Datacell Field line of products to include multi-pair Foundation fieldbus M-EZ (Marshalling EZ) cables. The cables are engineered with up to 24 individually foil-shielded pairs with an extruded PVC binder over each pair, all contained within a single cable. Datacell Foundation fieldbus M-EZ allows for fast, simple installation into marshalling cabinets and requires no shrink tubing.

All Datacell Foundation fieldbus cables are among the first to be FF-844 certified by the Fieldbus Foundation. This certification assures that the cable is electrically precise and meets Foundation fieldbus type A cable physical property requirements. Northwire has provided Foundation fieldbus cable for rugged petrochemical and other plant environments with networked process automation and control for more than 10 years.

All Datacell Foundation fieldbus versions are ITC (instrument tray cable)/PLTC (power-limited tray cable) rated for exposed-run (ER) applications and pass the same crush and impact tests for metal-clad cable (under UL 1569). ITC-ER/PLTC-ER cable allows users to do without the conduit when the cable is installed in accordance with recent National Electrical Code (NEC) amendments.

The line includes an arctic-rated ITC/PLTC-listed version with optional armour and a RoHS-compliant UL 1309 marine shipboard-listed cable with a cut- and abrasion-resistant TPE outer jacket; both are suitable for use to -60C. CSA, ABCD armoured cables are also offered. Datacell Foundation fieldbus cables are available as single-pair or multi-paired bus cables, with as many as 24 pairs in a single cable.

Shield options include individually foil-shielded pairs with drain wire as well as an overall foil with drain wire. Also, overall tinned copper braid is available for low-frequency noise immunity. The cable is offered in a variety of jacket and inner-conductor colours and options. Choices include 16 AWG - for longer runs - and 18 AWG in single-shielded, twisted-pair spur cables and as multi-pair cable. The cable is available with optional ground wire. The Characteristic Impedance Z0 is tightly controlled to be 100 ohms +/- 10 ohms; at 31.25 kHz.

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.
