2PCS Timer Relay Module External Trigger Delay On Off Switch Adjustable Timing Module

Feature: 1. Timer Relay Module: This module features high stability, accuracy and reliability; Power on and press the trigger switch to turn on load, and turn off load after delay time 2. Circuit Protection: Designed with reverse input protection and comes with a trigger key switch, this delay timer module protects against wiring errors while handling 10A loads 3. Adjustable Time Range: The time range is from 1 second to 10 seconds, adjusted by potentiometer; if you need longer time, simply replace a larger capacitor or potentiometer 4. Versatile Use: This timer module is suitable for robots, intelligent product development, automation equipment, PLC development, anti theft alarm delay, electronic development, etc 5. Compact and Functional: Measuring 67.6 x 19.2mm, this external trigger delay relay module is easy to carry and use in tight spaces like robot assemblies or alarm systems Specification: Item Type: Relay Module Product Material: Metal, Plastic Module Function: Connect the module power supply, press the key once, the relay will engage (the normally open and common terminals will be connected), and it will delay for 1 to 10 seconds (adjustable) before disconnecting. Working Mode: This module is a switch that instantly connects the trigger delay module. After powering the module, the power indicator light will turn on, and the output state of the module is normally open and common disconnected, normally closed and common connected; when the switch is touched briefly (or a high pulse signal is given), the working indicator light will turn on, and at the same time the relay engages. At this time, the output state of the relay is normally open and common connected, normally closed and common disconnected; after 0 to 10 seconds, the relay will disconnect, and at this point, the relay returns to the state before triggering. Applications: Suitable for robots, intelligent product development, automation equipment, PLC development, smart home, delay for alarm prevention, electronic development, etc. Module Size: Approx. 67.6 x 19.2mm 2.66 x 0.76in Control Load: Can Control Loads of 10A 250VAC, 10A 30VDC and below. Features: 1. The time can be adjusted by the potentiometer. The default setting is 1 10 seconds. If a longer time is needed, you can replace the capacitor or potentiometer with a larger one. 2. Anti reverse connection protection, with a trigger key, adjustable time, widely applicable. 3. There is a diode on the back of the module to prevent reverse power connection. Friends can connect it with confidence.. Package List: 2 x Relay Module
