The White Addressable Relay Base 6'' (PAD100-RB) is combination sensor base with a relay module included. The base has a locking feature for the sensor that may be used or removed in the field. Once the head is removed, the relay is accessible in the bottom of the unit. The PAD100-RB provides one form C relay output. The relay is rated for 2A @ 30 VDC, and 0.5A at 125VAC. The PAD100-RB provides for separation of high voltage and non-power limited connections from the power limited Signaling Line Circuit (SLC). The PAD100-RB does not consume an SLC address and does not require an auxiliary power source.
