Engineering SpecSheet SmaRT Base Unit BU-2H8D S Power FET Cutoff S Current Sense Capable S CAN Bus Capable S Weatherproof S Compact design S IEC 60950 Certified Features S 2.4GHz Spread Spectrum Technology S Eight FET Outputs/Inputs S High Side or Low Side Outputs S Diagnostic LED outputs S Two Analog Inputs/Outputs Capable S Single connector for ease of wiring The SmaRT Base Unit BU-2H8D features eight high-side or low-side switching FET outputs, each 3A max. It accepts a broad range of input power operating voltages (from 7 to 28VDC 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™ hand-held unit without the need to open the case. Using Direct Sequence Spread Spectrum (DSSS) wireless technology at 2.4GHz, the base unit provides a robust link with a SmaRT Hand-Held Remote in congested radio environments.
