RobG 1,891 Posted December 10, 2011 Share Posted December 10, 2011 I will have few of the following boards available very soon. All boards are 2" x 2". 1. Dual triac board - vertically mounted triacs, can be used with insulated or non-insulated triacs, mounting holes for triac and opto-coupler snubbers, space for heatsinks 2. Quad triac board - vertically or horizontally mounted triacs, can be used with insulated or non-insulated triacs, non-inductive loads or snubberless triacs bluehash 1 Quote Link to post Share on other sites
RobG 1,891 Posted March 7, 2012 Author Share Posted March 7, 2012 Boards are here, if anyone is interested, you can buy them from the store in few days. Will post pictures with assembled boards later today. Also, the 2 triac board has one more feature which is not on the original schematic, will make updates later today. bluehash and GeekDoc 2 Quote Link to post Share on other sites
RobG 1,891 Posted March 17, 2012 Author Share Posted March 17, 2012 Here are few ways to connect wires on the 4ch board: 1. solder wires directly to the board 2. angled terminals (horizontally mounted triacs) 3. plug-in type terminals Quote Link to post Share on other sites
bluehash 1,581 Posted March 18, 2012 Share Posted March 18, 2012 I love the terminals - red and green - perfectly complementing. Anyway, these will be available in the next week. PCBs only. Quote Link to post Share on other sites
krzyk2 11 Posted July 7, 2012 Share Posted July 7, 2012 I can't find those in the store, did they sold out? Quote Link to post Share on other sites

floridadrummer 1 Posted November 3, 2012 Share Posted November 3, 2012 Can you provide a bom for the dual triac board? Thanks! Quote Link to post Share on other sites
RobG 1,891 Posted November 3, 2012 Author Share Posted November 3, 2012 The BOM will depend on what you want to use this board for and on the triacs. Here's my BOM (post #2,) for non-inductive loads, light bulbs for example: Triac - BTA16-600BW - you can use BTA06, BTA12, and 600, 800, but use BTA (insulated) and W (snubberless.) Opto - MOC3023 - this is a random phase opto-triac, good for for dimming/PWM applications. If you want to just switch on and off, you can use MOC3043/MOC3063 which has zero crossing detector built-in. R13, R14 - 180ohm ( 1/4W or 1/2W is the best, but 1/8W should be no problem.) R1, R3 - 180ohm SMD0805 (can be higher, up to 300ohm should work OK.) R2, R4 - 270ohm SMD0805 (depends on the LED) LED - SMD0805 Terminal - DG300 or DG301 All other parts are optional and depend on the application. Except for LEDs, all of those parts are available from Tayda (non W triacs like BTA16-600B are OK.) GeekDoc, krzyk2 and floridadrummer 3 Quote Link to post Share on other sites
floridadrummer 1 Posted November 5, 2012 Share Posted November 5, 2012 I want to make a light dimmer, so this is perfect! Also, what heat sink did you use? Also, Do you happen to have a code example I could get started with? Thanks so much! Quote Link to post Share on other sites
RobG 1,891 Posted November 6, 2012 Author Share Posted November 6, 2012 You can get heat sinks from eBay, this one for example. Keep in mind that if you want to dim your lights, you will need to detect zero crossing. You will need another opto for that, preferably AC opto. I don't have dimmer code right now, but you can use portions of my light controller code. floridadrummer 1 Quote Link to post Share on other sites
floridadrummer 1 Posted November 6, 2012 Share Posted November 6, 2012 Rob, 2 more questions. How did you hook up the actual lights? It is hard to see from the video. Also, can I get your code that was used in the video above? I would like to get on off functionality going before I attempt the dimming... Thanks again! Quote Link to post Share on other sites
RobG 1,891 Posted November 7, 2012 Author Share Posted November 7, 2012 What you can do is cut one wire on the extension cord (preferably hot wire) and connect those cut wires to the board. If you want to use both channels, connect all neutral wires, the plug and both lights. Connect hot wire from the plug to X1-2 & X2-2 terminals. Connect hot wires from lamps to X1-1 and X2-1. The code in the video is nothing special, setup two pins as output and inside while loop, toggle each pin (P1OUT ^= BITx) then delay. Since you asked about dimmer code, I have written one that can control up to 8 channels (requires zero crossing detector.) I will post it once I test it. floridadrummer 1 Quote Link to post Share on other sites
RobG 1,891 Posted March 2, 2013 Author Share Posted March 2, 2013 I have a new version of this board and there are 2 major differences. 1. AC input & two AC outputs 2. Zero crossing detector reaper7 and Philipp 2 Quote Link to post Share on other sites

Philipp 56 Posted March 3, 2013 Share Posted March 3, 2013 This is the dual triac, correct? It is, you can tell by the number of triacs and by the labeling of the 5 pin header (2nd image) which reads Ch1-Ch2-GND-0xOut-Vcc. bluehash 1 Quote Link to post Share on other sites
