Flame Detector Alarm Relay Module Board 5VDC
Price in Sri Lanka

Electrical parameters:

• Supply voltage: 5VDC
• Load: 250V 10A AC or 30V 10A DC

Module instructions:

• The flame sensor is most sensitive to the flame and also responds to the sunlight. It is generally used for fire alarms and other purposes.
• By adjusting the potentiometer, the intensity of the sensor's induced flame can be set. When the flame exceeds the set threshold, the relay pulls in, the common end is connected to the normally open end, and when the flame is lower than the set threshold, the relay is turned off. The common end is connected to the normally closed end;
• Common end, normally open, normally closed three ports are equivalent to a dual control switch. When the relay coil is energized, the common end is electrically connected to the normally open end. When there is no electricity, the common end and the normally closed end are turned on;
• The sensor and the flame should be kept at a certain distance to avoid damage to the sensor at high temperature. The flame distance of the lighter is 80cm. The larger the flame, the farther the test distance is.
