1、Reliable Use: PLC like industrial grade circuit board, can remember set parameters when power failure occurs. 2、Stable Work: The output adopts optocoupler isolation to enhance anti interference ability and stable working. 3、Working Mode: After power on, connected a period of time and disconnected for a period of time, infinite loop. 4、Easy Setting: Enables a wide timing range from 0 to 999 minutes, and the operation is very convenient as well. 5、Durability: With a long service life more than 100,000 times, the time delay relay is very durable for long use. Item Type: Time Delay Relay Product Working Mode: After power on, connected a period of time and disconnected for a period of time, infinite loop (with normally open and normally closed contacts). Size: Approx. 65 x 36 x 18mm / 2.6 x 1.4 x 0.7in Output Capacity: DC 5~30V 5A, AC 220V 5A. Quiescent Current: 20mA Working Current: 50mA Working Voltage: DC 12V Service Life: More than 100,000 times. Working Temperature: -40~85℃. Function: The output adopts optocoupler isolation, enhances the anti interference ability and power consumption, and ensures stability. Industrial grade circuit boards, PLC like, after power failure set parameters can be remembered forever. 1 x Time Delay Relay
