1pcs chậm trễ on/off mô-đun chuyển đổi với bộ đếm thời gian DC 12V Chất lượng cao Rơle tác dụng chậm

This module is a delay module that uses main switches, touch switches, micro switches, and other normally open reset switches to trigger. It can also be triggered by normally open sensors, such as vibration sensors, reed switches, etc. It can form a vibration alarm sensing device. Mainly used in machinery and equipment, automation equipment modification, PLC industrial control, setting vibration alarm, robot, intelligent products. Product description: 1. Using high-quality timing chip control, accurate timing;2. Use high-power relay to control the load, up to 10A;3. It has a protection diode to prevent the power connection from being reversed to better protect the module;4. trigger terminal adopts optocoupler isolation, which has strong interference and interference ability and avoid false trigger;5. With 8 optional time ranges, as low as 0.1 seconds, as long as 1 hour; 6. Delay has potentiometer adjustment, clockwise adjustment time will be longer;7. With power indicator and delay switch indicator;8. The output of the relay usually has an open and normally closed interface. Features: Introduction of the normally open trigger function: before the module is triggered, the circuit at the end of the trigger is in an open state, if there is an immediate switch closure or continuous closure, this module can be triggered to delay the relay, and the relay is closed.1. The module is connected to the DC power supply and waits for the trigger terminal to see if there is a switch2 closed trigger signal. When the trigger terminal of the module senses that the switch is closed, the module will start the delay function, and the relay will close at the same time, and the delay will end, and the relay will be disconnected;3. When the module is triggered in the delay, if the trigger signal is received again, the module will restart and automatically trigger once until the delay is completed. The trigger end can support the following sensor trigger delay:1. Touch switch2. Micro switch 3. Self reset switch4. Normally open type vibration sensor5. Normally open reed switch6. Normally open the magnetic sensor door7. Tilt switch sensor8. Water level switch Electrical parameters: Power supply voltage: 12VDC Quiescent current: 4.8mA Power consumption: 70mA Trigger time: more than 1ms is enough Relay load capacity: 250V 10A AC 30V 10A DC (the actual application power is halved, which is beneficial to extend the service life of the product) Relay life: 100,000 times (power) Delay time range selection method: Switch S1.S2.S4 to different positions to select different time ranges, and the potentiometer is to adjust the time in the corresponding range
