I would like to install an X10 system to signal a functioning safety circuit for an CENTER PIVOT IRRIGATION SYSTEM, specifically the corner unit safety circuit.
The total length of the system is 1,200 to 1,400 feet. The signal could be sent down an unswitched 120 AC volt wire or one of three unswitched 480 volt 3 phase wires. Both cases would have unbroken neutrals.
At the X10 transmitter end when the corner unit safety is engaged a 120 volt relay is engaged. I would like to pick up this 120 volts as an activation signal to turn on the X10 transmitter and send the signal down the line to the control panel. Then the X10 receiver would turn on an LED light indicating the system is operational. Both end electronics are enclosed in water proof boxes.
Also water proof junction boxes are available every 200 feet if a booster or signal cleaner is needed.
I would like to keep the system simple. However if the technology available requires a step down of the signal to the transmitter to 5 to 20 volts AC or DC that process is doable.
I would like the LED light to be on as long as the safety latch is engaged.
120 volts or 5 to 20 volts AC or DC would also be available at the LED end.
I am quite excited that this project could save hundreds of dollars in trouble shooting and help myself and other irrigated farms optimize yields thereby saving water and fertilizer.
