Newsletter - August 2019 Raspberry Pi interfacing to Industrial and Wireless products There is a lot of
buzz surrounding the Raspberry Pi platform. Due to its eye-popping
capabilities and low price, engineers are investigating more
ways to use it in their designs.
The secrets to its
success are in price, performance, and flexibility. The Raspberry
Pi 3 Model B+ offers a 64-bit quad-core ARM processor, gigabit
ethernet, wireless, Bluetooth, 4 USB ports, micro SD slot, and
HDMI output. The power and capabilities of the Raspberry Pi is starting to be leveraged widely across industry. The success of the Raspberry Pi in processor intensive, professional engineering applications is why it is now being considered as an OEM option for industrial designs.
Low cost IIOT (for industrial not Commercial level). The OPTO 22 IO can absorb nasty industrial level noise and electrical abuse and still work. Like electric motors starting, VSDs and other noisy items. etc.

Newsletter - July 2019 Network, Switches and PoE Ethernet Switches and Media Converters Network Appliances, Gateways, Firewalls and Security MasTec carries a broad range of Industrial Grade managed and unmanaged Ethernet Switches and Fiber Switches and Media Converters. Between the manufacturing companies listed below, you will find exactly what you require for your industrial site and many IT sites also. If you need POE there is a growing selection. If you need EOP adaptors, we have these also. If you need Ethernet to Modbus gateways, we can provide quite a range to choose from. Many of our Wireless Routers and Gateways also container ethernet switches.
Some
with Ethernet/Fiber combinations. PoE (Power over Ethernet) technology is now very mature and still expanding in uses. POE is made possible by the injecting DC Power into some of the 8 wire in an Ethernet Cable. There are two types of POE Mid-span: +48VDC is delivered across the Ethernet cable using the unused pins (4, 5, 7 & amp; 8). End-span: +48VDC is delivered on on the same pins used for data (1,2,3 and 6). Usually POE is a high DC voltage > 24, sometimes much higher > 55 VDC. This injection usually takes place at the Ethernet Switch or with a POE Injector product. However now there are Computers and PACs that do the DC Power injecting also. At the far end of the Ethernet Cable an Etherent DC Splitter which brings out the DC and passes through the Ethernet data. The Splitters convert the POE voltage to standard voltages such as 48, 24, 18, 12 or 5 VDC. It is possible to pump quite a lot of power down an ethernet cable > 100 watts and still have reliability in DC supply. So imagine you are setting up video survellliance. All the cameras are 12VDC and TCP Gigabit Ethernet for the image data. Just plug the camera into the splitter for the DC power and the ethernet cable and you are done. You do not need to be near AC power to set up the camera, offering great placement freedom. The same is true of course for DAQ systems that have ethernet data connections, see some of the manufacturerss in the list of suppliers. POE is very convenient and saves a lot of installation time and money. If you are doing DAQ work there is no need for PSUs. Just plug the Remote DAQ into a splitter and ethernet data cable and you are done. And of course the Ethernet Cable is a great high speed data pipe for DAQ. Mastec has a LabVIEW system controlling 4 DAQ units running at full data rates of >100KHz each and the Laptop connected to the DAQ via a POE Ethernet switch, doesn't blink. |

DC Loads with AC Regeneration
Smart energy saving!
IT8300 Series Regenerative DC Electronic Load It not only can simulate various load characteristics, but also can feed power back to grid without pollution. IT8300 series unique regenerative function can convert the Battery Absorbed DC Power into AC power and feed it back to local grid. This can be single phase or three phase AC Power. This regeneration of the DC from the batteries back to AC power eliminates the usual heat dissipation experienced with most DC Loads (without Regen) to a minimum and saves energy costs, adapts requirements of global energy-saving and emission reduction at the same time. IT8300 adopts high power density design, e.g. for 3 U size, it can absorb power up to 10.5 kW. IT8300 supports master-slave paralleling and current equalized distribution, which can expand the power up to 105KW or more. Moreover IT8300 has multiple functions such as the automatic grid-state detection, on-grid electricity accumulation, anti-islanding protection, battery-test function, dynamic mode, LIST function, etc. The built-in interfaces include LAN/USB/RS232/RS485/CAN interfaces. The various functions make IT8300 series suitable for high-power power supply, storage battery, photovoltaic battery, electric vehicle, energy storage system, etc  feel free to email us. |
