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.
