Engineering SpecSh eet BU-9H20XF Base Unit, BU-2H20XF Base Unit Features S DSSS Technology (900MHz @ 10mW , 2.4GHz @ 100mW) S Weatherproof S CAN Bus Capable S 11 Diagnostic LEDs S Power Cutoff FET S Compact Design S 20 Dedicated FET Outputs/Inputs S Current Sense Capable S Four Character Display Option S PWM Control S Dual Connectors for Ease of Wiring S Translucent Case (reduced hole drilling) S Dual Analog Input Capable The versatile BU-9H20XF and BU-2H20XF base units feature twenty FET (field effect transistor) high-side switching outputs or switch-to-power digital inputs, and CAN Bus control capability. Ten channels are equipped with current sense for added control capability. The BU-9H20XF and BU-2H20XF accept a broad range of input power with operating voltages ranging from 7VDC to 28VDC. The rugged weatherproof enclosure allows these unit to operate worry free in harsh weather conditions. Two 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.
