WT9051

The WT9051 is designed as one kind of PIR (passive infra-red) controller that has some points of features:(1)high noise immunity; (2)drive either relay or triac; (3)adjustable light on duration; (4)triac can be either shunt or serial connected; (5)PIR input; (6)CDS input. This device is the most stable PIR controller you can find on the market. More than this, there are few components needed in its application circuit which can reduce material cost and increase competitive.

The electrical characteristics of WT9051 can be summarized as:(1)supply voltage: 14 V;(2)SDA Input Voltage: -0.2 to Vcc V;(3)SDA Output Sink Current: 10 mA;(4)SCL Input Voltage: -0.2 to Vcc V;(5)VSAW Output Source Current: 4.5 mA;(6)VSAW Output Sink Current: 4.5 mA;(7)E/W Output Source Current: 4.5 mA;(8)VEI Input Voltage: -0.2 to Vcc V;(9)HEI Input Voltage: -0.2 to Vcc V;(10)PWM Output Sink Current: 10 mA;(11)V.DF Output Source Current: 4.5 mA;(12)Fly Back Pulse Input Voltage: -0.2 to Vcc V;(13)Horizontal Output Sink Current: 10 mA.
