^Diagnostic LEDs STwo Analog Inputs ^Weatherproof S Compact design BU-x00H Base Units (BU Features S2.4GHz or 900MHz DSSS Technology SH-Bridge Motor Control SThree FET Input/Outputs SDual connectors for ease of wiring SRS232 OR CANbus Capable The SmaRT BU-x00H base units features an H-bridge (25A max.) for forward/reverse motor drive, three FET high-side switching outputs or switch-to-ground digital inputs, and two analog inputs (typically for monitoring use). The versatile, programmable digital input/outputs can be customized by Cervis to fit specific user applications. It accepts a broad range of input power with operating voltages ranging from +7 to +18VDC. The rugged weatherproof enclosure allows the unit to operate worry free in harsh weather conditions. Two 12-wire color-keyed weatherproof connecting cables connect the controlled devices. SmaRT base units feature seamless association to SmaRT hand-held remotes without the need to open the case. Using Direct Sequence Spread Spectrum (DSSS) wireless technology at 2.4GHz or 900MHz, the base unit provides a robust link with SmaRT hand-held remotes in congested radio environments. The unit also features a choice of factory configurable CANbus or RS232 communication port.
