2.4 GHz radio module for remote control of equipment in industrial applications

Circuit Design Inc, a design and development company of radio modules has developed an input module (NT-4M) and an output unit (NR-1) set. Designed to be embedded into user equipment, the system transmits switching signals. Planned release for users of industrial remote control applications is set for the third quarter of the year.

With a fast input-output response time of 10ms and using continuous transmission, it is ideal for controlling electric motors. Also, frequency hopping (FH) is used in the original protocol allowing multiple transmission systems to be operated in the same area together. For example at a distribution center, remote control can control several loading and unloading operations at the same time without interference, even in the presence of many cars and other vehicles.    For use worldwide, NT-4M, NR-1 has adopted the use of the 2.4 GHz band. To use in the Japanese market, the module complies with the Japanese standard ARIB STD-T66 and obtains technical regulation conformity certification. The units meet the regulations of FCC and EN, making them possible to be used in the overseas market.
