MCC Offers Bus-Powered USB-To-I2C-Bus Adapter

The I2CStick from Micro Computer Control (MCC) is a bus-powered USB-to-I2C-bus adapter for on-the-go mobile developers, test engineers and field-support personnel. The user plugs the pocket-sized I2CStick into a laptop's USB port, connects to an I2C-bus target device and starts communicating. The I2CStick supports 7-bit slave addressing, bus master or slave operation at standard (100kHz) or fast (400kHz) clock rates and multi-master and arbitration detection capability.

The device is 3.3V to 5V compatible, provides switch-enabled bus pull-ups and a 5V power source for external devices and includes over-voltage, reverse-voltage, electrostatic-discharge and dual-stage fuses for laptop or desktop computer protection. Free utility software includes MCC's Iburner I2C-bus EEPROM programming software and the Message Center messaging software. Application developer support includes a .Net Class Library, the Labview Virtual Instrument Library, the ASCII-Text application program interface (API), the Virtual Communications Port (VCP) interface and sample software projects in VB, C, C++ and MFC.

VCP drivers are available for Windows, Linux and Mac. The I2CStick's API compatibility extends to other MCC I2C-bus adapters, including Iport/USB, Iport/AFM and Iport/AI. Typical applications include product hardware/firmware/software development, manufacturing tests, in-system EEPROM programming, field-service diagnostics and repair and firmware updates. Prices range from USD150 (GBP98) to USD250 depending on interface cable configuration and order quantity.

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.
