CIRCUIT Design, represented by Telelink Communications , has developed a full lineup of the industrial use radio transceiver module STD-302, with 434MHz, 869MHz (EU), 458MHz (UK), 447MHz (Korea), 429MHz (Japan) and 419MHz (China) versions.
The pin assignment in all frequency versions is the same so that by changing the frequency program to suit the various frequencies, the user is able to provide products that meet the radio regulations of each country.
The STD-302 achieves an accelerated TX/RX switching speed of 5ms, a level that was difficult to obtain in the past with FM narrowband (<25kHz step) multichannel transceiver radio modules.
The fast switching speed means the STD-302 is finding applications in the field of industrial use telecontrol as a remote radio control unit incorporating an answer-back function, an area where time delays are not acceptable during the operation of equipment.
