AR-B104D Module Ideal For Automation Applications

Acrosser Technology has launched the AR-B104D PCI-104 interface CAN bus, 24 digital channel I/O and SRAM module for automation and in-vehicle applications. The CAN bus controller on the AR-B104D confirms to Bosch spec CAN 2.0B Active. It provides reliable communication up to 1Mbps baud rate with sample wiring. The CAN controller handles error detection and re-transmission, which simplifies programming.

The 12-channel digital inputs of AR-B104D provide optical isolated general purpose input function and are also able to be a counter input. Users do not have to handle the state change event when they have to count the pulses that come into the digital input. The 12-channel 500mA digital outputs can also operate as automatic pulse generators as well as general purpose outputs. In many applications there is critical data that has to be stored in real time and very frequently, and it is important that this data is not lost when external power is suddenly disconnected.

SRAM memory with battery back-up is ideal for this application because of characteristics including fast access and unlimited write cycles. The AR-B104D is also equipped with 512K bytes battery-backed-up SRAM memory. It can operate as a solid-state disk as well as general-purpose memory. A free software development kit comes with the AR-B104D package, including device drivers, API, sample code, demo program and a software programming guide to support Windows and Linux operation systems.

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.
