Delay Switch Connect Module Adjustable Time Delay Relay with On and Off Indicator 12V

Features 1、When power-on or an external key switch is triggered, the relay delay is adjustable from 1 second to 10 minutes. The relay contact is opened or closed. 2、With relay on and off indicator 3、When the time action is less than about 0.5 seconds, the relay is turned off to protect the delayed drive IC. 4、Elliptical design of mounting holes for quick and easy installation 5、Delayed turn-on of the power supply that can be used to control the high-voltage screen of a tube amplifier 6、Monostable working mode, externally connected with a normally open button, can perform conventional monostable control 7、Applicable to other occasion that require delay control, can be used for access control 8、Multiple circuit modules are combined together to achieve linkage delay control, intelligent control, and simple PLC control Specification Item Type: Delay Switch Module Input Voltage: 12V Input Current: Greater than or equal to 50MA. 1 Second to 3 Minutes Delay Board: 470UF capacitor Instructions: 1. Blue potentiometer, turn CW to shorten delay time, turn CCW to lengthen delay time 2. After the delay time is set for this delay board, the trigger delay is performed as soon as the power is turned on (the indicator is on). Triggering again at this time will delay again. Immediately after the trigger (a short time), a “click” sound is heard, and the continuous trigger has a continuous “click” sound, which indicates that the delay has reached the shortest time is 0 seconds. At this time, you can adjust the potentiometer CCW and trigger again, Slowly adjust to the required delay time. 3. Remember: The power supply cannot be greater than 12V, and the positive and negative of the power supply cannot be reversed. Package List 1 x Module
