5/12/24v 1CH Auto Circuit Modifications Voltage Comparator LM393N Module A2TF
Function One: enter a Voltage comparison with setting reference voltage, when the input voltage is greater than the reference voltage, the relay closed; when the input voltage is less than the reference voltage, the relay no action. Function two: enter two voltage signals A&B being compared, When Signal A greater than signal B, relay closed; when Signal A less than Signal B, Relay no action. Module Application: Auto circuit, household equipment, remote controls, industrial testing, and so on. Operating voltage: DC5/12/24v Working current: 60mA Standby current: 15mA Standby power consumption: <0.5W 1. Input(+) 2. Input(-) 3. Delay output indicator, LED will light on when the Relay connect. Light Off when relay Disconnect. 4. Jump shorting JP1, the relay public-pin have same voltage with pow.
