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 power input.
Disconnect JP1, the relay public-pin uncharged (default settings).
5. Relay normally open Pin.
6. Relay public Pin.
7. Relay Normally closed pin.
8. Functions two Jumper settings, when you want to use features-two need disconnect Jumper.
9. Adjustable resistor, adjusting the reference voltage, reference voltage value can be test through the 10-pin.
10. Comparison reversed-phase input (-)
11. The comparator inverting input (+)
