Download | Software: SVN browse |
Platine mit 4 galvanisch getrennten Triac Ausgängen für Phasenanschnitt (z.B. für Glühlampen, Halogenlampen mit Transformator (keine elektronischen)). Eingang für Nulldurchgangserkennung. Muss an EXT 2 angeschlossen werden (ICP PIN).
Auf dem labnode läuft der SVN:can_dimmer.
CAN:
function 0x00 - 0x04 lamp 0x00 - 0x03 brightness 0x00 - 0xff
- destination port:1
- 1st data byte is the function (0x00-0x04)
- function 0x00:
- toggle lamps, switch to next pattern, called by the light button in the room
- function 0x01:
- set lamp (2nd data byte) brightness to value (3rd data byte)
- function 0x02:
- fade all lamps, called by the light button in the room if held
- function 0x03:
- toggle direction for fading, called by the light button in the room if held and then released
- function 0x04:
- enable/disable (3rd data byte), disable == 0 brightness, enable == [saved brightness (function 0x01)] lamp (2nd data byte)
- function 0x00:
- 1st data byte is the function (0x00-0x04)
TODO:
- replace MOC3020 with MOC3023
- add RC snubber to limit dU/dt !
- add choke to limit dI/dt !
- oder man nimmt einen snubberless triac z.B. BTB 08/600BW
Hints
- The resistor in front of the LEDs might be changed according to voltage of the LEDs - watch out: LEDs current has to match the current of the optotriac
- optotriacs with zero crossing detector are NOT suitable for dimming ;)
