18-function time delay relay module, timer cycle, self-locking relay for home automation, 12V automatic control

Beschreibung Time Delay Relay Module 18 Functions Timing Delay Cycle Self Locking Relay Control Module for Smart Home Automatic Control 12V Item Type: Time Delay Relay Module Product Material: PCB Module Console: 3 Wire Interface, All Interfaces Have Terminals DC+: Positive Pole Of DC Power Supply DC-: Negative Pole Of DC Power Supply CH1: Input Detection Interface, Active High Relay Output: 3 Wire Interface, All Interfaces Have Terminal Blocks NO: Relay Normally Open Interface, The Relay Is Suspended Before Closing, And Short Circuited With COM1 After Closing COM: Relay Common Interface NC: Relay Normally Closed Interface, Short Circuit With COM1 Before The Relay Picks Up, And Hangs After Picking Up1、18 Kinds Of Functions: Newly upgraded to version 2.0, the module functions have been increased from the previous 8 to 18 to meet more application needs. 2、Power Supply Anti Reverse Connection: Increase the power supply anti reverse connection function, so that the module will not be damaged due to wrong power connection. 3、High Withstand Voltage: The high withstand voltage power supply module is used to replace the previous discrete power supply, and the system is more stable and reliable. 4、0.1s Timing Function: Added 0.1 second timing function, and the timing accuracy has been upgraded from 0.1 second to 0.01 second. 5、Automatic Power Saving: Add automatic power saving function, users can set it by themselves.The user can select one of the following 18 functions through the keys and display, and can set and save the function parameters, as well as view the parameters of the current function. Instructions for setting operations can be obtained from the seller. Tips: Functions 1?8 will start automatically when powered on, and functions 9?18 require a high level pulse signal (the high level duration is not less than 20ms, the same below) to trigger the start.1 x Control Module
