Pepperl+Fuchs Announces Remote I/O Systems

Designed to facilitate the connection of traditional input and output signals onto a bus network, Pepperl+Fuchs has introduced the LB/FB remote I/O systems. LB/FB systems support general-purpose or intrinsically safe applications with modules that can be mixed and matched on the same backplane. These systems facilitate connection to Profibus DP, Modbus and Foundation fieldbus for all traditional signal types, including discrete, analogue, frequency and temperature.

Redundancy for the communication interface and power supply ensures high reliability. 'Anyone using a traditional intrinsic safety barrier can benefit from LB/FB remote I/O systems, as they allow barriers to be pushed into Division 2 and Zone 1 hazardous areas,' said Brian Traczyk, Pepperl+Fuchs product manager. 'These remote I/O systems are also suitable for upgrades and expansions and can be beneficial when devices such as thermocouples or RTDs do not have a fieldbus interface,' he added.

LB/FB remote I/O system users are said to benefit from: reduced wiring; fewer DCS control cards; fewer terminations for reduced installation costs; and reduced control cabinet space requirements. Faster commissioning LB systems are rated for Division 2 mounting with inputs and/or outputs mounted in a Division 1/Zone 0 area. FB systems are designed for intrinsically safe or increased safety applications and rated for Zone 1 mounting with inputs and/or outputs mounted in a Zone 0 area.

With LB systems, IS and general-purpose modules can be mixed and matched on the same backplane. LB systems include a backplane, communication interface, power supply and I/O modules. They can be DIN Rail mounted or Pepperl+Fuchs' Systems and Solutions Group can pre-mount the system in an enclosure specified by the user.

With FB systems, IS and increased safety modules can be mixed and matched on the same backplane. FB systems include a backplane/enclosure, communication interface, power supply and I/O modules. The system comes installed in the user's choice of enclosure with GRP, fibreglass and stainless steel as standard options. FB systems are available with a number of optional accessories that can be mounted within the enclosure to extend its functionality, including terminal blocks, fuses and disconnect switches.

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.
