Features: Timing range: 0-999seconds, 0-999minutes, 0-999hours, three kinds can select the desired. Feature Sets: delay, timing, cycle18 kinds of combinations of features. The product can be used for timing, delay, cycle timing, intermittent timing, etc. The product can be used for timing switch, and the control panel of the timer alarm. Maximum working current is 10A, maximum power is 1500W. Specifications: Product size: 3 x 9.7 x 5.2cm/1.1 x 3.8 x 2.0 inch Time range: 0-999s / 0-999m / 0-999h Maximum working current : 10A maximum power: 1500W Voltage: DC 12v Weight: 70g Instruction Manual: Before using the first prompt the user to note that a certain set of data After waiting 6s, 6s after the memory module will automatically save the data set. (1) Press SET key to enter the time setting mode, the digital tube flicker, buttons plus or minus buttons to adjust the timing T 1 and the timing T 2, after setting the time, must wait 5s, 5s after the module will automatically remember save data. (2) Press SET, the parameter setting mode. There are two sets of parameters for the user to select P0, P1. In the current mode Short press SET to switch P0, P1. In P0, P1 parameter can be set for their own timer mode through the key addition and subtraction. P0--0: timing mode is 0--999 ??seconds P0--1: timing mode is 0--999 ??minutes P0--2: timing when the pattern is 0--999 ?? hours P1--0: T1 time delay relay (T 1 timer) P1--1: T1 delay time relay releases (T 1 timer) P1--2: time delay relay after T 1 (T 1 timer), then the delay time T 2 successor electrical release (T 2 timing) ends. P1--3: T1 delay time relay releases (T 1 timer), then the delay time T 2 successor Electric energized (T 2 timing) ends. P1--4: time delay relay after T 1 (T 1 timer), then the delay time T 2 successor electrical release (T 2 timer), repeat the cycle. P1--5: T1 delay time relay releases (T 1 timer), then the delay time T 2 successor Electric energized (T 2 timer), repeat the cycle. Package Included: 1 x Timing Delay Relay
