2x 12V Infinite Cycle Delay Time Timer Relay Turn ON OFF Switch Loop Modules HOT

Adjustable from 0 to 15 minutes Voltage: 12VQty:2pcs Feature: This module uses MCU as the main chip. High time accuracy MCU watchdog circuit and special reset chip. Fine workmanship and good performance. Stable and reliable work. Long service life. T1 (the relay switch-on delay time), T2 (the relay switch-off delay time) One-time mode (Jumper OP3 1. The module will turn on when the relay is tripped, T1 delays and the relay disconnects. 2. If it is triggered on the re-triggered delay operation, it will immediately interrupt the delay. Cycle Mode (Jumper OP4 1. The module power-on, when triggered, the relay is turned on, delay T1, and the relay is disconnected, delay T2. The relay is switched on again. Such a cycle. T1 and T2 are each set by two adjustable resistors. 2. If it is triggered on the re-triggered delay operation, it will immediately interrupt the delay. Typical Application Reference 1. Timer operation equipment, like everyone press key trigger when you reach 5 minutes the automatic shutdown. 2. Repeat the test circuits, such as for 1 minute, and then turn off such a test cycle for 1 minute. 3. Fish Tank Pump Intermediate Feed Pump Oxygen. 4. Other time control equipment. Performance: 1s-15min Version: Jumper OP1: 1 to 100 seconds, 0.1 seconds control accuracy. Jumper OP2: 1 second to 15 minutes, 1 second control accuracy. The time delay error of all kinds of temperature and humidity is not more than 2%. Package Included: 2 x Timer Relay ON OFF Cycle Modules Hint: The object
