Radio Modules For Industrial Use

Compact narrowband radio modules for industrial use, now with multiple channels Circuit Design, Inc., a leading supplier of narrowband radio modules, has launched small multi-channel transmitter CDP-TX-05M-R and receiver CDP-RX-05M-R. These include nearly all the parts necessary for industrial-use radio transmission in a small and robust shielding case. They are both compatible with the CDP-TX-04S-R transmitter and CDP-RX-03AS-R receiver, earlier models of the same modules that were very well received in the Japanese and European markets for their quality and reliability. They also come with several new functions. While the earlier models had just one RF channel, the new models are programmed with four channels. In addition, within the main ISM frequency band of Sub-1 GHz, the frequency table can be customised according to the customer's requirements. Using a TCXO as the reference oscillator circuit of the radio component ensures high frequency stability, and while the operating temperature range of the earlier product was -10°C to +60°C, in the new product it is increased to -20°C to +65°C. With the output of 10 mW authorised for narrow band FM and double superheterodyne receivers with high receive sensitivity in the European harmonized ISM band, a communication range of 600 m (line-of-sight) is possible. Applications: industrial remote control; security and alarms; telemetry and monitoring systems; and tracking systems.
