BU-9H8D Series Base Receivers

The Cervis SmaRT™ Base Unit BU-9H8D features eight high-side or low-side switching field effect transistor (FET) outputs, each 2.5 A max. It accepts a broad range of input power operating voltages (from 7 to 28 VDC standard). All connections are made via a single cable, and the rugged weatherproof enclosure allows the unit to operate worry free in harsh weather conditions.

SmaRT™ base units feature seamless association to a SmaRT™ handheld unit without the need to open the case. Using Direct Sequence Spread Spectrum (DSSS) wireless technology at 900MHz, the base unit provides a robust link with a SmaRT handheld remote in congested radio environments.
