Engineering SpecSheet BU-xH1R Base Unit Family Features SDSSS Technology 900MHz @ 10mW, 2.4GHz @ 100mW S One Form C Relay SUp to Five Form A (SPST) Relay Outputs Standard Operation SSingle Connector for Wiring Ease ^Diagnostic LEDs SCAN bus Capable SWeatherproof Case 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-xH1 R family of base units accepts a broad range of operating input power with model dependent operating voltages of 7-32VDC, 7-28VAC, and 100-240VAC. 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 to a SmaRT hand-held unit without the need to open the case. Using Direct Sequence Spread Spectrum (DSSS) wireless technology at 900MHz or 2.4GHz, the base unit provides a robust link with a SmaRT hand-held remote in congested radio environments with a line-of-sight communications range of up to 1,000 feet. 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.

The wiring configuration shown is for a BU-xH1R5 — no CAN connection. For CANbus BU-xH1R3, P7 is CANH and P9 is CANL. JP5 when installed (factory) isolates the Form A relays from the Form C relay. SNote: Cable shields should be grounded only at one end of each shield segment to minimize ground loops. SNote: BU-xH1R-CAN units are internally terminated at 4.3kn. Termination can be removed at the factory. SmaRT BU-xH1R Base Units November 2015
