The ZULU-T868 Telemetry Module provides a reliable RF transceiver based industrial Remote Switch. Each unit is supplied ready to operate and once paired with another module, a remote control/sensing system is created. Power supply, antenna and input/output are the only connections required. The ZULUEVAL-T kit (RS 762-0121) consists of two development boards with ZULU-T868 modules, one set up to be a transmitter, the other a receiver.
