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.
There is currently much discussion around the term "platform," which may be preceded by the adjectives "mobile," "wearable," "medical," "healthcare," etc. However, regardless of the platform being discussed, they usually have one key aspect in common: They tend to be wireless. So, why is this one aspect so fairly universal? The answer is convenience.
Everyone has a MEMS story. For most of us it’s probably the airbag that saved our lives or the life of a loved one. Perhaps it’s the tire pressure sensor that alerted us about deflation before we were stranded alone on a dark muddy road.
Bioimimicry is not merely a helpful design tool -- it also encourages designers to think not only about how to solve design problems by imitating nature, but how to make the products, materials, and systems they design more ecologically sound and nature-friendly.
