Hi guys,
As I'm new to the whole forum set up I hope I've come to the right place for some assistance.
At present I have one irrigation timer used to control a 220V pump via a relay.
I now want to connect a second irrigation timer to the same relay, using the same coil input contacts.
As each timer will have its own 220V / 24Vac power supply transformer I'm concerned that there will be a back flow of power between the two irrigation timers.
One option would be to install a second 24Vac/220V relay, (this will will involve some major digging work)
A Second option would be to install a diode in both the timer output cables.
I'm I correct with the idea of fitting diodes or what would you recommend.
The irrigation timer out put source is 24Vac - 300 mAmp.
What type & size diode must I install?
Thanks
