Robocraze DC 6V To 30V One Way Relay Module Delay Power Off Disconnection Trigger Delay Cycle Timing Circuit Switch | 1-Channel Power Relay Module with Adjustable Timing Cycle

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. (1)xxx. if the decimal point is in some place, the time interval is s-1 999 s (2)xx. x is the decimal place is ten, the time interval is 0.1 s 99.9 s- (3)x. x. x is the decimal point are all on, the time interval is 1 min-999 min How to set the parameter: First, make sure relay operation mode According to the operating relay mode, the main interface (power module will flash current operating mode; standard mode P1.1, then come into the main interface); long press SET key two seconds and then choose and enter selection interface mode; by pressing UP, DOWN key to choose the mode setting (P1.1 ~ P4) After selecting the mode, press short SET to set the corresponding parameter, then the parameter you want to set will flash (OP power in time; CL power off time; LOP cycle times, is unlimited cycle ); by UP, DOWN to set the parameter value, support long press (increase or decrease quickly) and press slightly (increase or decrease of 1 unit); after setting the parameter value by short press the STOP key to choosing decimal place; choose the time interval (corresponding time interval is 0.1 s-999 min); Short press SET to set the current mode next parameter, the process is the same as above After the setting mode parameter, press and hold the SET button then hold the current configuration mode will flash, then go back to the main interface; define success parameter main interface: when the relay does not work, it will show 000 (no decimal point); the operating state relay, the screen has a decimal point Mode Select Interface: press and hold the SET key to enter; after setting, long-press the SET button back on the main interface Activate Relay Mode: NO: PO in power over time, the relay can be connected OFF: relay is not allowed to connect, when in the off state in short main interface press the STOP key to achieve turn ON and OFF, the current state will flash; then back to the main interface (this function is a function of a sudden stop, 1 key to turn off the relay) Sleep Mode: C-P Sleep mode: within 5 minutes, no operation; nixie tube will close auto display, and a function program well Note: 1. 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. Specifications :- Operating Voltage (VDC) 6V ~ 30 Supply Current (A) 0.05 Trigger Voltage (VDC) 5 Switching Voltage (VAC) 250@10A Switching Voltage (VDC) 30@10A Operating Temperature (C) -40 to 85 Storage condition () -40 to 80 Length (mm) 63 Width (mm) 38 Height (mm) 18 Weight (gm) 26

The quality is nice and working perfectly

nice circuit

it is a rip-off!! You can get the same module for Rs. 150 on Amazon. It came without any manual, but if you look around, you will find procedures on how to program it and the connections. Bottom line, the product is good, but the price is high. Today I noticed that none of the P2 timers are programmable with the new module. Since I need only P1.1 timer for my project, I am keeping it. This product is not consistent because the earlier module worked well (With that, relay was not working) Anyways the module works for my project so keeping it.

This really a useful module. The best part is the time settings are stored even the power is turned off. But the counter will be reset once the power is rebooted to the module. I am using this module to control to switch on the cooling fan for certain period of time and turn it off.

Ok but 5v not warking

Excellent timer switch. Built quality is too good. Working fine. Very easy to setup. Find the setup instruction from youtube if you don't know how to setup. I have used this for school science project. Price is good. I loved this product.

Overall good product under these prices and I got my delivery very next day on time. I was expecting USB power cable and user manual with it, but unfortunately it was not in the packet. I suggest if you share a user manual to your customers it will help them a lot. I can recommend this to my friends...
