Tal -----Original Message----- From: pic microcontroller discussion list [mailto:PICLIST@MITVMA.MIT.EDU]On Behalf Of Lucas Hartmann Sent: Friday, January 30, 2004 9:02 PM To: PICLIST@MITVMA.MIT.EDU Subject: Res: Re: [EE] DIAC question Your circuit seem to use the diac to detect voltages above 10V on the line and trigger the transistor and relay. Right? Try replacing the diac for a single 10V zener(Katode to the capacitor). This will give you pretty less signal on the transistor's base, so you may need to lower R2(wich is already a pot.) or R3 a little.
