It is time to dig up the yard and put in a sprinkler system. I would like to use a Dallas 1-Wire Switch to control each solenoid. The idea is to run the 1wire net, power and ground with each pipe run. That way the system can be extended at any point.
I have been looking for an appnote on interfacing to the DS2405 PIO pin.
I need to understand how to get the DS2405 Addressable Switch to power the solenoid? A mechanical relay is not an option. I plan to pot the circuit for the obvious reason.
Solenoid Specs
The device controlling the solenoid is the
Dallas DS2405 Addressable Switch
If I futz with it I might come up with something that works but I need a solution I can trust.
I would like to keep the cost down if possible.

Solenoid Specs
24Vac 60HZ nominal
19Vac 60HZ min
Inrush 0.3 Amps 7.2VA @ 24 Vac 60Hz
Holding 0.2 Amps 4.8VA @ 24 Vac 60Hz
The device controlling the solenoid is the
Dallas DS2405 Addressable Switch
PIO pin sink capability is greater than 4mA at 0.4V
The PIO outputs are configured as open-drain and provide up to 20mA continuous sink capability and off-state operating voltage up to 28V. Control and sensing of the PIO pins is performed with a dedicated device-level command protocol. To provide a high level of fault tolerance in the end application, the 1-Wire IO and PIO pins are all capable of withstanding continuous application of voltages up to 28V max.
