Triac - Detection DIP4 pin type ZC triac optocoupler to G pole with a negative trigger signal SCR BT136S-600E, the resistance value should be around ten Euro patch SCR, prove pipe has been turned on, turned direction T1 a T2. Then the red tip and G pole disengaged (but still connected to T2), if the resistance value remains unchanged, proof tube after the trigger to maintain the conduction state. Triac - product identification TRIAC equivalent to two-way thyristor reverse parallel connection. That is one way in which a silicon anode and cathode of the other side is connected SCR, said its terminals T2 pole, one of them the other way silicon cathode and anode connected to its terminals, said T2 pole, and the rest compared with a control electrode (G) SCR | n Wal Electronics (certified) | SCR provided by the Dongguan City is fertile Electronic Technology Co., Dongguan City is Wo Electronic Technology Co., Ltd (www.dgmydz.com) (www.dgmydz.com) Dongguan, Guangdong, FET leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, the maximum Limits to meet customer needs. Wal-e-leadership in the positive with the staff warmly welcome all inquiries negotiations to create a positive fertile electronic better future.
