[chbot] Opto isolated triacs - Digikey account anyone?

[Jasper Mackenzie]

Heya Robin,
 Please excuse my probable deep ignorance, but why do you not use a very
standard MOC3041?? Available at.. well everywhere! (Sicom have them locally)

Am using a mix of MOC3041 and MOC3063 in my solar hotwater controller for
pumps and heaters... they are very reliable, unlike other parts 8)
