- The relay output of the RG-11 is
rated for 24V AC or DC, at 1 A. Thus,
the RG-11 cannot drive a line voltage
(120 VAC) load without an external
relay.
-The RG-11 requires a low voltage AC
or DC supply and may not be directly
powered from the 120 VAC line.

For this example, these
switches are on:
SW 5 - Sets the sensor to
“It’s Raining’ mode.
SW 3 - Monostable extend
output for 15 mintues.

In many cases, the RG-11 may directly replace
tipping buckets in existing systems.
The switch settings shown here- all off– will
emulate a tipping bucket of 0.01”
