Engineering SpecSheet SmaRT BU-xH24XF Base Unit Features S DSSS Technology (900MHz @ 10mW , 2.4GHz @ 100mW) S Weatherproof S CAN Bus Capable S Five Diagnostic LEDs S Two Analog Outputs S Four Analog Inputs S Sixteen FET Outputs/Inputs S Eight Current Sense Channels S H-Bridge S Power Cutoff FET S Two Form C Relays S Quad Connectors for Ease of Wiring with Power on Each Connector The versatile BU-xH24XF base units feature an H-Bridge, sixteen FET (field effect transistor) high-side switching outputs or switch-to-ground digital inputs, two Form C relays, and CAN Bus control capability. The BU-xH24XF accepts a broad range of input power with operating voltages ranging from 7VDC to 28VDC. The rugged weatherproof enclosure allows these units to operate worry free in harsh weather conditions. Four 12-wire color-keyed weatherproof connecting cables connect the controlled devices. Using Direct Sequence Spread Spectrum (DSSS) wireless technology at 900MHz or 2.4GHz, the base unit provides a robust link with a SmaRT handheld remote in congested radio environments. SmaRT base units feature seamless association to SmaRT hand-held remotes without the need to open either the handheld remote or base unit.
