The SmaRT BU-XH6R Base Unit features six Form C relay outputs. Each Form C relay contact can switch up to 8 amperes at 250 VAC or VDC. Using Direct Sequence Spread Spectrum (DSSS), the base unit robustly links with a handheld remote control unit in congested radio environments at extended ranges. All controlled apparatus connections—and base unit power—are made using two cables with keyed, heavy duty 12-pin connectors, through which output signals are also ported. Five status/diagnostic LEDs shown in Figure 1 below determine the state of the unit.
