Feature: 1. Wide voltage power supply (6-30V) supports micro USB 5.0V power supply, which is very convenient to use. 2. Clear and simple interface, powerful function, easy to understand, almost meet all your needs. 3. Has a key emergency stop function (STOP key), with reverse connection protection, reverse connection does not burn. 4. Increased sleep mode, enabled, within 5 minutes without any operation, automatically shut down the display; any key wake-up. 5. Different OP, CL and LOP parameters can be set. These parameters are independent and stored separately. 6. All setting parameters are automatically saved after power failure. 7. With optocoupler isolation, enhance anti-jamming ability, industrial grade circuit board, set parameters after power off forever memory. Specification: Working Voltage: 6-30V Supports Micro USB 5.0V Power Supply Trigger Signal Source: High-level Trigger (3.0V-24V) signal is not in common with the system to improve the anti-jamming ability of the system (also can be connected to the ground by itself) Output capability: can control equipment within 30 V 5A DC or 220 V 5A AC Static Current: 20mA Working current: 50mA Service life: more than 100,000 times Working temperature: - 40 - 85℃ Size: 62*38*17mm/2.44*1.49*0.66'' Packing weight: 28g Working Mode: P1: When the signal is triggered, the relay turns on the OP time and then disconnects; in the OP time, the following operations are performed. P1.1: Invalid signal trigger again. P1.2: Signal triggers recount. P1.3: Signal triggers reset again, relay disconnects, stop timing. P-2: Give the trigger signal, after the CL time of the relay is disconnected, the OP time of the relay is turned on, and after the timing is completed, the relay is disconnected. P3.1: Give trigger signal, after the relay turns on OP time, the relay turns off CL time, and then circulates the above action. The signal is given again in the cycle, the relay turns off and stops timing; the number of cycles (LOP) can be set. P3.2: No trigger signal is needed after power-on. The relay turns on OP time, the relay turns off CL time, and the above actions are recycled. The number of cycles (LOP) can be set. P-4: Signal holding function if there is trigger signal, time zero, the relay keeps on; when the signal disappears, the relay is disconnected after timing OP; during timing, there is signal again, time zero. Note: Relay output is passive contact, no live output, control a line on-off role. Please allow 1-3mm differs due to manual measurement. Due to the different display and different light, the picture may not show the actual color of the item. Thanks for your understanding. Included: 1 X 1-Way Relay Module 1.
