ABB Launches Small PLC Solution For Automation

The AC500-eCo provides a small PLC solution for industrial automation applications, particularly as part of a standalone environment. The selection is said to offer a cost-effective solution for smaller projects. The AC500-eCo has been designed to enhance the flexible and scalable concept of the AC500 PLC line. Part of the AC500-eCo package is a range of communication options, including Modbus master/slave or CS31. 

The 128kB user memory and a program-processing time of 0.1us/instruction are two examples of the AC500-eCo's performance. In addition to its interoperability with the existing AC500 range, the AC500-eCo system is configured and programmed using the PS501 Control Builder AC500 - based on Codesys. This programming software for the whole AC500 range complies with the EN 61131-3 standard, including five programming languages to provide customers with a single, simple and integrated software platform. With three new CPU and four new IO devices, ABB continues to expand the AC500-eCo offering. 

For example, the CPU versions offer integrated digital and analogue inputs and outputs, along with relay outputs. CPUs can be provided in 24V DC or 100-240V AC power-supply versions, according to the customer's requirements. Relay and triac output modules, together with a 100-240V AC digital input module, are added to the S500-eCo IO range. The IO module DX571, which combines digital inputs and relay outputs in one module, allows customised application solutions. The simple system structure, standardised interfaces and programming environment are said to allow quick and easy configuration.

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.
