UHF narrow band telecommand modules

Paul Boughton
LPRS, the supplier of short-range radio devices, has announced the availability of the multi-channel telecommand transmitter and receiver modules.

In addition to the high performance narrow band FM (MSK) wireless design, the modules offer four selectable pre-programmed communication channels and 6 switch signal input/output processing circuits, allowing switch signals to be transmitted and received without the addition of external components. A simple control system may be quickly realised by connecting a switching board to the CDT-TX-02M-R transmitter.

The new CDT-TX-02M-R and CDT-RX-02M-R modules offer long range control, low voltage operation with low current consumption for reliable battery operation and CDT-01-compatible communication format. Output switching is via very reliable Photo MOS relays and all circuitry is housed in robust metal casings.

These CE certified radio modules operate in the 434 MHz ISM band and offer  the following standard features; six switch inputs and outputs, transmitter standby mode in, four receiver operation modes, 10mW RF output power, MSK modulation, receiver sensitivity -120 dBm, six switching signal transmission R&TTE (EN 300 220)  and RoHS compliance. Power requirements for the CDT-TX-02M-R are 2.2-12 V @ 27 mA with 1 µA at standby and for the CDT-RX-02M-R, 3.0-12V.

Typical applications for the new CDT-TX-02M-R and CDT-RX-02M-R telecommand modules include remote control applications, paging systems, emergency lights, alarm systems and start/stop control for motor operated equipment including shutter blinds, garage doors, gates etc.

In addition to the wide range of narrow band long range wireless modules from CDT now available from LPRS, the latest generation of their own market leading easyRadio Advanced (eRA) wireless modules is proving highly successful.
