5V 12V 24V DC Infinite Cycle Delay Timer Relay Turn On-off Switch Loop Module

Description:
It is a timer relay module with high precision, stable and reliable performance.
Support 2 modes, mon mode(once) and cycle mode, and you can simply switch mode by adjusting the jumper.
There are many voltage and time range for your choice, both "on" time and "off" time are adjustable.
It is great to control the reciprocating stroke, or repetitive power on and off for equipment and products burn-in test.
Widely used on timer operating equipment, machine repetitive test circuit, fish tank intermittent pump, etc.

Specifications:
Type: (Optional)
  • DC5V,0-15min/0-60min/0-24h
  • DC12V,0-15min/60min/0-24h
  • DC24V,0-15min/0-60min/0-24h 
Max. Load Capacity: 10A250VAC, 10A30VDC
Size: 70*20mm / 2.75*0.78"
Time Error: <2%
T1(the relay turn on delay time),T2(the relay turn off delay time)

Once Mode(Jumper OP3):
1. The module Power-on, When triggered the relay is switched on, delay T1, and the relay disconnected.
2. When triggered on the delay process, again triggered, it will immediately interrupt the delay.

Cycle Mode(Jumper OP4):
1. The module Power-on, When triggered the relay is switched on, delay T1,and the relay is disconnected, delay T2, the relay is switched on again. Such cycle. T1 and T2 are set by two adjustable resistors, respectively.
2. When triggered on the delay process, again triggered, it will immediately interrupt the delay.

How to Set Time Quickly:
Time can be quickly set by measuring voltage(Uc) of resistor. Take a 5V 15min module as example. If Uc=2V, time=2V/5V*15min=6min.
 
Application reference:
1. Time-limited devices, e.g. automatic power-off after 5 minutes per key trigger
2. Repeated testing of machine circuits, e.g. power on for 1 minute and then power off for 1 minute and so on
3. Fish tank pumps for intermittent pumping of water and oxygen
4. other time control devices
 
Performance indicators:
Jumper OP1: 1 second to 100 seconds, adjustment accuracy 0.1 second
Jumper OP2: 1 second to 15 minutes, precision 1 second
Time delay error at various temperatures and humidity not exceeding 2%

Package Included:
1PC*Timer Relay Module
