What kind of cable should I use?

For laying in the garden, use a “telephone underground cable”, eg “A-2YLY2 diameter 0,8mm”. This is available from 4 to 20 cores.

FOR AC:

FOR DC:

FOR LATCH:

Thicker cables allow longer line lengths. Applies to standard valves with approx. 300 mA inrush current as well

for AC an AC power supply with >= 36VA power (at 24VAC max 1,5A)
with DC and latch a DC power supply >= 20W (at 7,5V-12V, approx. 2,7A)

The cable of the solenoid valves must be connected to this cable in a watertight/waterproof manner, e.g “3M Scotchlok 314 ”

What kind of solenoid valves can we work with?

• AC powered OpenSprinkler (including OSPI) works with standard 24VAC sprinkler system valves. It is compatible with existing 24VAC systems including pump start relays, wireless sensors that require 24VAC power. 24VAC valves open when energized and close when de-energized.
• DC powered OpenSprinkler Works with both 24V AC sprinkler system valves as well as 12 VDC (non-latching) valves. It comes with a 2A power adapter, enough for 4 valves. However, for certain 24VAC pump start relays and wireless sensors that require large amounts of 24VAC power, you may need to provide a separate 24VAC power supply. 24VAC or 12VDC valves open when energized and close when de-energized.
• Latch OpenSprinkler works only with DC magnetic latch valves. These are self-locking valves that require an impulse for each change of state.
