RLE SD-RO1

The SD-RO1 is a single zone spot detector with one relay output.  It can be used in conjunction with any product that accepts a digital dry contact input.

Spot detectors are ideal for small spaces, and are the most economical way to detect fluids in confined areas, such as condensation drip pans.

Note: The SD-RO1 requires an isolated 24 volt power supply. RLE recommends and stocks the WA-AC-24-ST. The PSWA-DC-24 may also be used, but if a DC power supply is used the SD-RO1 will be a latching device – once an alarm is detected, the spot detector will remain in an alarm state until power is cycled to the SD-RO1. Power supplies are available for purchase separately.
