Serial Radio Transceiver
The SEL-3031 is a 915 MHz ISM serial data radio that supports point-to-point (P2P) and point-to-multipoint (P2MP) operational modes. In P2P mode, the SEL-3031 supports three serial data ports in one radio channel. The ports are completely independent and support a mix of protocols, including DNP3, Modbus, Mirrored Bits communications, SEL Fast Message, plain ASCII, and more. In P2MP mode, a one-channel master radio communicates with multiple remote radios for supervisory control and data acquisition (SCADA) or other data-gathering applications. SEL Hop-Sync technology optimizes collocated radios applied as multiple point-to-point links or as active repeaters. The SEL-3031 is a low-power device using less than 5 W in the wall-mount version, allowing it to be incorporated into recloser controls, such as the SEL-651R. A standard 1 RU high rack mount version is also available, all backed up by SEL's no-questions-asked, worldwide, ten-year product warranty.
