2.5 CERTIFICATION AND WARRANTY
•
Underwriters and FCC approved.
•
Manufacturer’s limited 5-year warranty.
2.6 ELECTRICAL SPECIFICATIONS
•
Input power: 105-130 VAC, 50/60 Hz, ½ Ampere maximum, 0.1 Ampere idle.
•
Output power: 24 VAC, 1.5 Amperes maximum total output or 36 VA maximum
total output 1.0 Ampere per station or Master Valve.
Table 1 - Electrical Calculations
Valve solenoids are rated in either Amperes or VA. The term VA stands for Volt-Amps,
which is obtained by multiplying the Amperes required by the 24 VAC operating voltage.
Most modern solenoids require approximately .25 Ampere, which is equivalent to 6 VA.
This allows up to six solenoids to be energized at the same time.
EXAMPLE: You are using a Master Valve and Pump; you have configured the system to
use the NO STACK option. This configuration would allow all four
programs to run simultaneously, as depicted in Figure 6 – Master Valve and
Pump Electrical Connections.
Four programs (.25 A times 4) 1.00 Ampere
Master Valve (.25 A times 1) .25 Ampere
Pump using Rain Master RLY1 (.20 Amps) .20 Ampere
Total Current 1.45 Amperes
NOTE: This configuration would not exceed the 1.5 Amperes maximum allowable
limit.
If higher current solenoids are used or if more than one solenoid is connected to any one-
station output, caution should be used when operating in the NO STACK configuration
mode.
