Positioner Operates in Hazardous Environments

Inmoco has launched the Exlar EXP-24 positioner for tasks such as valve control, shipboard fuel management systems, fuel skids, refineries, engine test stands, paint booths and printing presses. Conforming to both Atex (Directive 94/9/EC) and CSA regulations for explosion-proof applications, the EXP-24 complements Exlar's EL100 actuator, providing an integrated control/actuator package in hazardous process environments and can also be used to drive most three-phase linear actuators and rotary motors.

Housed in an IP66-rated enclosure, the EXP-24 positioner integrates a fully featured 24VDC motion controller and brushless servomotor amplifier, and is able to power most resolver feedback brushless motors. Ideal for process control applications, the EXP-24 provides the functionality to position a valve or damper by following an analogue input signal. Four additional motion modes are also available to accommodate a range of motion control applications.

Designed with an isolated RS485 Modbus serial interface to facilitate integration into factory-wide process systems, the EXP-24 employs the latest sinusoidal space vector commutation to ensure excellent actuator/motor performance and provides motion setup features such as move distance, jogging and homing, plus a range of diagnostic features including real-time monitoring, following error, position error and communications diagnostics. Setup of the EXP-24 is simplified with an operator control panel and via Windows-based software. The software provides users of the EXP-24 with the means to simply select all aspects of configuration and control required to operate the EXP-24 positioner.

Further setup help is delivered by tabbed pages that provide access to input all of the parameters necessary for configuration of valve control or general motion applications. The explosion-proof rating, high performance and environmental packaging of the EXP-24 mean that the positioner is suitable for a range of applications. Inmoco's products are used in robots, machine tools, automation, metal bending, handling, packing, textiles and paper. They are backed up by comprehensive application and service facilities.

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.
