The BRAVO-T868 is a 868MHz radio telemetry module in SIL package. This module provides a reliable transceiver based industrial remote switch with up to 1000m range. Two or more modules may be combined to provide a simple or complex network of radio switches. Each module can be set to act as a transmitter or receiver. A telemetry system is achieved when two modules are paired together, as transmitter (BRAVO-Tx) and receiver (BRAVO-Rx). Each time any input changes on the BRAVO-Tx, it will transmit the status of all inputs to the paired BRAVO-Rx(s). The BRAVO-Rx(s) which will set their outputs to match the BRAVO-Tx inputs. After each state change the modules will return to sleep mode.
