Wiring
V+ module DC powered positive
GND The DC supply of the module is also the reference GND of the signal voltage.
IN signal voltage input, low level below 1V, high level above 1.5V, uncertain in the middle. Up to 30V
Normally open contact of the NO relay
Constant contact of NC relay
COM relay contact common
Instructions
Time range setting
– When the selector switch is placed in the 30 position, it means 0-30 adjustable
– When the selector switch is placed at position 300, it indicates that 0-300 is adjustable.
Adjustment of time value
– Adjustable resistance rotates counterclockwise to the direction of the number to reduce the time, clockwise to the + direction increases the time
Time unit setting
– When the selector switch is placed in the Sec position, the unit is:second
– When the selector switch is placed in the Min position, the unit is:minute
Example
Request a delay of 50 minutes
1. The range is placed at 300 position
2. The time unit is placed in the Min position.
3. Adjust the adjustable resistance to 50 position, adjust to 300, so adjust to 1/5 is 50.
Note:The potentiometer adjustment can also be quickly adjusted with the multimeter voltage file. For example, the range is 30, and it needs to be adjusted to 12, then the voltage can be adjusted to 2.
t=Ut/5*30=2.0V / 5.0V * 30 =12
Ut is the voltage measured by the multimeter, 30 is the range selected by the selector switch, and can also be selected to 300.
Applications
Combined with the travel switch and the inductive switch
1. Timeout automatically closes the door
2. Pipeline product flow monitoring
3. Current flow monitoring such as water flow
4. Other uses
