News » Product News Wireless footswitch uses new comms technology
The German safety specialist steute has developed a two-channel wireless communications technology designed to be reliabie and to operate effectively in the same area as other wireless systems. The system, called sWave 2.4GHz-safe, is based on a pseudorandom frequency-hopping technology with the hopping pattern known only to the transmitter and receiver.
Two-stage residual current relays will reduce shutdowns
Residual currents can occur in industrial plants as a result of various problems including: inadequate insulation of terminals or cables; humidity; contamination; or ageing materials. Simple monitoring relays are available that raise and alarm or trigger a shutdown when they detect a rise in residual currents.
Drive controllers reach the sixth generation
The German geared motor and drive systems manufacturer Stöber has expanded its modular drive and automation portfolio with a sixth generation of its drive controllers and motion controllers that use the Codesys v3 programming and controlling software. The two types of controller can be combined to create a drive controller that can be operated in a controller-based mode.
WEG adds modular contactors to LV switchgear portfolio
At the recent Hannover Fair, the Brazilian motors and controls manufacturer WEG emphasised the breadth of its low-voltage switchgear portfolio, with several new arrivals including lines of modular contactors and motor protection circuit-breakers.
ABB's drives family continues to expand
ABB is continuing to expand its ACS880 family of drives which made their debut in 2011. It unveiled several new developments unveiled at the recent Hannover Fair.
Phones and tablets become easy-to-configure and use HMIs
The Californian automation manufacturer Opto 22 has announced a new way to build and deploy simple, scalable operator interfaces based on computers and mobile devices such as smartphones and tablets.
Up to 64 integrated servodrives can be powered from one supply
At the recent Hannover Fair, Danfoss unveiled an integrated servodrive based on a permanent-magnet synchronous motor sharing an enclosure with the drive electronics. The VLT ISD 510 drives cover rated torques from 1.7–15Nm and are equipped with Ethernet-based EtherCat and Powerlink communications.
I/O system squeezes 20 channels into 12.5mm-wide modules
The Austrian automation company Sigmatek has developed a compact modular I/O system that fits up to 20 channels in a 12.5mm-wide module. The rail-mounting S-DIAS modules – which include safety versions – communicate using a real-time Ethernet system called Varan with a bus speed of 100Mbit/s. The I/O modules can be accessed within 1.12µs.
Next-generation light curtains ‘set new standards’
Sick has announced a new generation of safety light curtains that, it says, set new standards for efficiency, ease-of-installation and reliability. The deTec4 Core curtains have no blind zones, offering optimum positioning and protection against unsafe access, while allowing operations to continue efficiently.
HVAC drives incorporate a fire mode
Following the recent launch of its CFW500 variable-speed drive, WEG has announced a variant dedicated to HVAC pump and fan duties. The compact, easy-to-use CFW501 drives span the power range 0.18–7.5kW and there are plans to increase this to 22kW next year.
Encoder-free IP55 drives can be wall-mounted
SEW-Eurodrive has developed a decentralised frequency inverter for controlling the speeds of asynchronous and synchronous motors without an encoder. The IP55-protected Movitrac LTP-B drive can be wall-mounted, even in difficult ambient conditions.
Ex-rated IE4 motors are ‘world’s first’
At the recent Hannover Fair, Bauer Gear Motor launched what it claims is the world's first Ex-rated, IE4 super-premium efficiency geared motor. It adds that the S Series PMSMs (permanent magnet synchronous motors) are the world's most efficient motors for use in explosive atmospheres.
Hygienic cables and detectable energy chains ensure food safety
igus has launched a pair of products – anti-microbial cables and plastic energy chains containing easy-to-detect metal particles – designed to help food manufacturers to produce food that is safe for consumption.
Sinewave filter ‘solves inverter-driven motor issues’
The Canadian power quality specialist Mirus International has developed a technology that, it says, marks a substantial step in mitigating harmonic issues associated with inverter-driven motors. The Inversine AUSF (advanced universal sinewave filter) is designed to transform chopped-up PWM VFD output voltages into clean sinewaves with a THD (total harmonic distortion) of less than 3%.
Ethernet cable links IPCs to HMIs up to 100m away
At the recent Hannover Fair, Beckhoff announced a technology that allows an operator panel to be located up to 100m away from an industrial PC (IPC) and linked to it via standard Ethernet Cat 7 cable, thus cutting cabling and installation costs. The single-cable CP-Link 4 technology can carry DVI video signals, USB 2.0 serial communications and a 24V power supply, allowing the remote displays to be passive.
