The is a SIL RF Telemetry Module with 868MHz frequency band provides a reliable transceiver based industrial remote control for use as a modem or a bidirectional switch. GAMMA is easy to use with direct no-volt Switch input and direct switching telemetry outputs and serial data in/data out. The GAMMA uses the latest OFDM, spread spectrum technology and extensive algorithm enhancements to achieve an industry leading 16km 10mile range. Two or more modules may be combined to provide a simple or complex network of radio controls and/or radio modems. It is suitable for use with remote control and networking, remote switching and remote traffic light applications.
