SmaRT BU-xH1R Base Unit
The SmaRT BU-2H1R5 and BU-9H1R5 base units feature one Form C relay output and five
Form A relay outputs. CAN bus capable base units
—BU-2H1R3 and BU-9H1R3—have one
Form C and three Form A relay outputs. The BU-xH1R family of base units accepts a broad
range of operating input power with model-dependent operating voltages of 7
–32 VDC, 7–28
VAC, and 100
–240 VAC. All connections are made using the single 12-wire cable harness that
fits to the base unit keyed connector to guard against cross connection.
SmaRT base units feature seamless association with a SmaRT handheld unit without the need
to open the case. Using Channel-Hopping Direct Sequence Spread Spectrum (DSSS) wireless
technology at 900 MHz or 2.4 GHz, the base unit provides a robust link with a SmaRT handheld
remote in congested radio environments with an extensive line-of-sight communications range.
BU-9H1R3 and BU-2H1R3 CAN units provide a CAN bus interface for applications requiring
wired connectivity.
The rugged weatherproof enclosure allows the unit to operate worry-free in harsh weather
conditions.
