    • Description
    • Features

    The STD-502-R is a radio transceiver module for control of industrial machines. The STD-502-R 2.4 GHz transceiver is used worldwide and complies with the ARIB, CE, and FCC standards in Japan, Europe, and the U.S. 

    Designed to be embedded in equipment, the STD-502-R was developed as a radio module for industrial applications that require reliable operation. With battery operation, it achieves line of sight radio communication beyond 300m. Besides using highly noise-resistant direct-sequence spread spectrum (DSSS) modulation, the module has a true diversity receiver function for preventing signal dropout due to multi-path fading. This ensures highly reliable radio communication in the congested 2.4 GHz ISM band.

    The module itself has no built-in communication protocol. Instead, it has a transparent data input/output interface, enabling users to employ their own protocols without modification. In addition, it can continuously transmit a LOW or HIGH signal without restriction, which was not possible with earlier models. Circuit Design developed its own ASIC with DSSS modulation and a true diversity function in order to guarantee the long-term supply of key radio components required for industrial devices. Therefore, the STD-502-R is not reliant on components from other companies for its main functions.
