Review: Good timer circuit. I'm using it for cooler pump to on off at intervals. - Very good timer circuit. Without user manual is hard to understand. I found one that helped me. Here is the info: Operation Mode: P1: Trigger signal, the relay is on OP time, and then disconnect; Within the OP time, proceed as follows: P1.1: the signal is triggered again, invalid P1.2: the signal is triggered again, re-clocking P1.3: Signal has triggered again, the relay is disconnected, stop the clock; P-2: Trigger signal, after the CL time is off, the OP time is on. When the timing is completed, the replay will be disconnected; P3.1: Trigger signal, after the OP time is on, the CL time is off, then cycle the above actions. If trigger signal within the loop, the relay will be disconnected and stop the clock. The number of cycles ( LOP ) can be set. P3.2: No need to trigger the signal after powering up, the OP time is on, the CL time is off, then cycle the above actions; The number of cycles ( LOP ) can be set. P-4: Signal holding function. If the signal is triggered, timing is cleared, the relay remains on; when the signal disappears, the relay will be off when the OP time is over; if another signal is triggered during timing, timing will be cleared. How to choose the time interval: parameter Introduction: OP power over time, turn off time CL, LOP cycle times (1-999 times, is unlimited cycle) 1. In the selection of parameter set interface mode, and press the STOP button to select the time.

Press and hold the STOP button for 2 seconds can achieve change from C-P to O-d; Current state will flash and then return to the main interface 2. The relay contact is passive and electricity production; 1 channel has the control function on / off Features: Optocoupler Isolation: improve the anti-interference ability, after the parameter setting, it will be in memory forever. Wide voltage power supply (6 ~ 30V), supports micro USB 5.0V power supply, easy to use. The interface is clear, simple, powerful and easy to understand, can meet almost all your needs. With emergency stop function (STOP button) and reverse polarity protection which can avoid burning by reverse connection. Adding sleeping mode, when the mode is enabled, if there is no operation within 5 minutes, the display will be turned off automatically, press any button will wake it up; You can set different parameters of OP, CL, LOP, which are independent of each other and are stored separately; All the parameter settings will be stored automatically when power is off.
