Corporation from 1962 to the late 2000s (decade), and were largely responsible for giving rise to the widespread use of automatic irrigation. The first model was the ME11AB, capable of running 11 stations on two schedules. A scaled-down residential model, the RC-8, was formally introduced in 1968 and was marketed as the "first appliance for the garden".

, planning on adding the cost of the system to the mortgage. The controllers were used in controlled experiments of swine waste lagoon systems. The product line would later range from compact 3-station mechanical units to 23-station multi-program devices.
The Rain Clox series controllers were known for their durability. In 1997, Rain Bird held a contest to find the oldest functioning controller, eventually locating an RC-8 manufactured in 1964 which was still functioning after it survived a tornado.[ A considerable online aftermarket for the controllers has appeared following their discontinuation.

RC
Dual-schedule controllers with individual switches for each station to run on either A or B program. Rain Bird later resurrected this design as the "Turfmaster".

*RC-8
*RC-12
*RC-18
*RC-23
RC-A
These featured a single 14-day watering schedule and 23 possible on-the-hour start times. The RC-A series controllers were later replaced by the RC-B (indoor) and RC-C (outdoor) series following improvements in mechanical design.
*RC-4A - 4 stations, 1–60 minutes.
*RC-7A - 7 stations, 1–60 minutes.
*RC-1230A - 12 stations, 1–30 minutes in 1-minute increments
*RC-1260A - 12 stations, 2–60 minutes in 2-minute increments
RC-AB
These consisted of two RC-A series controllers in one unit which operated in sequence, with the capability of switching off the lower controller on a given day. Zones requiring less watering would thus be assigned to the lower unit. The 12th station on the upper unit was replaced with a tripper mechanism to start the lower unit.
*RC-1830AB - 11 stations, 1–30 minutes in 1-minute increments; and 7 stations, 1–60 minutes in 1-minute increments.
*RC-1860AB - 11 stations, 2–60 minutes in 2-minute increments; and 7 stations, 1–60 minutes in 1-minute increments.
*RC-2330AB - 11 stations, 1–30 minutes in 1-minute increments; and 12 stations, 1–30 minutes in 1-minute increments.
*RC-2360AB - 11 stations, 2–60 minutes in 2-minute increments; and 12 stations, 2–60 minutes in 2-minute increments.
MC
Master control units for golf courses, consisting of a single RC-A unit which operated three separately timed sets of stations.
*MC-3S - Three sets of 12 stations (36 total), 1-10 minutes.
