Do all sprinkler timers come with a 24-volt connection that goes to a contactor to start the irrigation pump?

Most all controllers have a pump control port, but in most cases that only sends a signal to a separate Pump Start Relay that matches to the specific pump in horsepower and voltage to actually start the pump running. In some controllers the 'Master Valve' port may double as a pump control.
