Transformer 120v/60hz to 12vac 60 hz used with many Autotrol valves in the U.S.A.
PN 1000811 and newest PN 3019151


Used with the 440i low voltage and 460i electronic timers ( and a few other timers - include older 960 and newer 740 and 760 Logix ).
Plugs into a small jack located on the Timer.

We sell the 440i HV timer, and it is 120 volt ready to plug in and does not require this transformer.
