Middletown, Pa., March 24, 2011—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. In addition, 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 1-watt, 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 secure.

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 simple, IT-friendly embedded software. The entire family is listed for use in Class I, Division 2 hazardous locations.
