Phoenix Contact has added a basic
version of the Trusted Wireless Ethernet (TWE) radio. The TWE-Basic
(RAD-ISM-900-EN-BD/B) transmits Ethernet data from remote locations, even in
high interference environments.
The "basic" nature of the product
indicates the removal of the standard RS-232 and RS-485/422 ports. The
TWE-Basic is a "slave-only" device, so it must be used in conjunction with a
standard TWE or TWE-BUS radio acting as the master. Like the other Trusted
Wireless radios, the basic version features the MOTR-9 radio platform, a 1W,
frequency-hopping spread spectrum (FHSS) transceiver. It operates in the
license-free 902-928 MHz ISM band. The MOTR-9 radio lets the user configure
over-the-air data rates up to 500 kbps. Adjustable packet sizes maximize data
speed and minimize latency. The radio also incorporates selectable
128/192/256-bit AES encryption to prevent unwanted intrusion and keep data
The TWE family also includes the
RAD-ISM-900-EN-BD and the RAD-ISM-900-EN-BD-BUS. Both of these modules are
freely configurable as a master, slave or repeater and include RS-232/422/485
ports for integrating serial devices into IP-based networks. The bus version
also features an integrated expansion bus for connecting analog, digital and
pulse I/O modules that are addressable via Modbus.
Any network PC with a web browser can
configure the devices via embedded software. The entire family is listed for
use in Class I, Division 2 hazardous locations.
What makes this movie stand out from the typical high school sports story is that the teenagers are undocumented immigrants, and the big game is a NASA-sponsored marine robotics competition. Like many other Hollywood movies, however, Spare Parts only tells part of the story. What the film shows -- and doesn’t show -- raises important issues affecting STEM education in the US.
Instead of sifting through huge amounts of technical data looking for answers to assembly problems, engineers can now benefit from 3M's new initiative -- 3M Assembly Solutions. The company has organized its wealth of adhesive and tape solutions into six typical application areas, making it easier to find the best products to solve their real-world assembly and bonding problems.
Load dump occurs when a discharged battery is disconnected while the alternator is generating current and other loads remain on the alternator circuit. If left alone, the electrical spikes and transients will be transmitted along the power line, leading to malfunctions in individual electronics/sensors or permanent damage to the vehicle’s electronic system. Bottom line: An uncontrolled load dump threatens the overall safety and reliability of the vehicle.
