Feature:1. Industrial grade single chip microcomputer is used to control the time, with high accuracy and stable performance2. With two adjustable resistors to adjust the time, the on-off time can be adjusted independently3. Start timing by external contact activation and selfreset button short circuit, convenient and fast4. The start timer will shortcircuit the trigger and start the countdown when the power is turned on. If it is triggered again during the operation, the connection will be immediately disconnected.5. The time range is divided into 0 ~ 100 seconds, 0 ~ 15 minutes, 0 ~ 30 minutes, 0 ~ 60 minutes, 0 ~ 120 minutes, 0 ~ 24 hours and other specifications, which can meet different needsSpecification:Item Type: Delayed Circuit Module Material: ResinModel: HCW-03Typical Application Reference: 1. Time-limited working equipment, such as automatic power-off after 5 minutes each time a button is triggered2. The machine repeats the test circuit, for example, power on for 1 minute and then power off for 1 minute.3. The fish tank pump intermittently pumps water and oxygen4. Other time control equipment .Package List:1 x Delayed Circuit Module
