Web-IO 4.0 Time Switch 4xIn/Out - TOP-electronics

57735 - Web-IO 4.0 Time Switch 4xIn/Out

Time switch in the network - timed switching according to centralized specifications

With the 57735 Web-IO Time Switch, switching processes can be controlled according to the specifications of an iCal calendar file.
The calendar file can either be loaded into the Web-IO via the web interface or the Web-IO can call up the switching times independently from an online calendar, e.g. Google calendar or Apple iCloud.
The four switching channels can also be used as an input. Changes to the inputs can then for example be forwarded via email or FTP or displayed directly in the browser.

Possible applications:

  • Remote monitoring and fault messaging
  • Cross-location switching
  • House and building automation
  • Light, gate and cabinet control

EveryWord™ Audio Front End (AFE) Far-Field Voice Module - TOP-electronics

Getting to know the EveryWord™ AFE module - ArkX Labs

With the Ark-X analogue front-end which contains the full audio codecs, microphone interfaces and DSP for full voice-recognizing based on Amazon, Google or Sensory.
The sensitivity is very impressive where the human ears aren’t able to hear the wake word, the AFE is able to listen in noisy environments and withing 10+meters.

This is good for applications like; Manufacturing-production safety, intercom to the front-desks for meeting-rooms and hotels, Agriculture control system when you need an extra hand.

The module is compact, and can listen to 2~4 microphones at the same time while it is able to determine the direction of the audio signal.

With a powerful DSP on board it is possible to have 3D audio processing technology, and is there all kinds of interfacing, like: USB, GPIO, SPI, I2C and MIPI and I2S for audio.

TVS DIODES - TOP-electronics

TVS Diodes - Fuzetec

TVS Diodes are electronic components designed to protect sensitive electronics from high-voltage transients. They can respond to overvoltage events faster than most other types of circuit protection devices, and are offered in a variety of surface mount and through-hole circuit board mounting formats.

These TVS Diodes can fit a wide range of circuit protection applications but were primarily designed to protect I/O interfaces in the telecommunication and industrial equipment, computers and consumer electronics.

Features SMBJ series

• Glass passivated chip
• 600 W peak pulse power capability with a 10/1000 µs waveform, repetitive rate (duty cycle) : 0.01%
• Low leakage
• Uni and Bidirectional unit
• Excellent clamping capability
• Very fast response time
• RoHS compliant

PA12 - Power Op Amp - 90V, 15A peak - TOP-electronics and Apex Microtechnology

Apex PA12; 40 years and still going strong

Apex Microtechnology introduced the PA12 linear power operational amplifier in the early 1980’s.

This part is still one of their fast runners and produced in big quantities. With 90V, 15A peak it is a real general purpose product, also available in military grade and high temperature versions.

Over the years there have been many updates due to components obsolescence, but the datasheet specifications are still unchanged. This is one of the very strong points of Apex; hardly any product gets obsoleted, which is a dream in today’s quick changing world.

Other strong points and benefits of Apex:

  • One product on the BOM instead of many discrete components
  • Reduced time to design; Quick time to market
  • Excellent thermal management
  • Smaller, lighter, proven; small power density
  • 100% ATE tested
  • Documented performance
