Low-Power Radio Modules For Electronics Design

Radiometrix will exhibit wideband and narrowband low-power radio modules for the electronics design community at National Electronics Week on 18-19 May at the NEC in Birmingham. The company, which will be found in Hall 1 at the event, will also unveil its SHX1 narrowband transceiver. Powered by a +5V regulated supply, this compact, multi-channel-operation VHF device has an output power of 500mW, allowing it to cover a range of more than 5km.

The transceiver is usable in any 3MHz segment of the 140-175MHz frequency range, allowing it to be employed in wireless communication based on the 144MHz amateur, 151MHz US Multi Use Radio Service (MURS) and European 169MHz bands. The standard module can offer data rates of up to 5kbps and supports eight parallel or 255 serial channels. It conforms to both the ETSI EN 300 220-3 and EN 301 489-3 electromagnetic compatibility standards.

As the SHX1 has separate N and R registers on each channel for transmit and receive functions, the frequency of each of these channels can be individually programmed in every mode. This transceiver is suitable for a variety of end applications, including amateur radio, MURS units, industrial/commercial telemetry systems, high-end security alarms, automatic packet reporting systems, vehicle data upload/download and remotely operated vehicle/machinery controls.

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.
