Falling edge - triggered. Initial state after power no voltage output, once triggered, output terminal output the poiwer supply votage, after once again trigger the output terminal no voltaged output, and so on. Low standby power consumption, high output power, good anti-jamming performance optocoupler isolation. Electrical parameters:Power supply voltage:DC 3V-24V;Standby current:less tahn 2uA;Allowing continuous output current:5A(when the power supply voltage 5V-24V),4A(when the power supply voltage 4V-5V),2A(when the power supply coltage 3V-4V);Size:free pin size 16mm x 10mm x 7mm. Pin pitch 22.54mm;Uses:LED electronic switch;Note:The drive inductive load, the load to the appropriate freewheeling diode in parallel to avoid damaged to the switching elements of the circuit.Pin definitions:VCC:power supply;VO:output;Tg:trigger signal input terminal;GND:power ground.Included:1 x Module
