Features How to Use: Users can select one of the following 20 functions by pressing the button and display, and can set and save functional parameters, and you can also view the parameters of the current function. 3 Options: 2 -way Multifunctional electromagnetic relay module has 5V, 12V and 24V modules to choose from, which can meet your multiple needs. Accuracy: The time parameter setting of multi -function electrical relays can be adjusted at least 0.1 seconds, and the accuracy is better than 0.01 seconds. Open the Maximum Load Capacity: Self -locking loop time Time relay usually turns on the maximum load capacity of the end port: DC 0‑30V/10A, AC 0‑250V/10A. Turn off the Maximum Load Capacity: 2 Low relay switches the maximum load capacity is usually closed: DC 0-28V/10A, AC 0‑125V/10A. Specification: Item Type: Time Delay Relay Module Control Terminal: There is a 3-wire interface, all interfaces have wiring terminals, which is convenient for users to use 1. DC+: DC power supply positive (5V, 12V and 24V modules are available) 2. DC-: negative pole of DC power supply 3. CH1: Input detection interface 1, active at high level 3. CH2: Input detection interface 2, active at high level Relay Output Terminal: 6-wire interface, all interfaces have wiring terminals 1. NO1: Relay normally open interface 1, hang in the air before the relay is closed, and short-circuit with COM1 after it is closed 2. COM1: Relay common interface 1 3. NC1: Relay normally closed interface 1, short-circuit with COM1 before the relay is closed, and hang in the air after being closed 4. NO2: Relay normally open interface 2, hang in the air before the relay is closed, and short-circuit with COM2 after it is closed 5. COM2: Relay common interface 2 6. NC2: Relay normally closed interface 2, short-circuit with COM2 before the relay is closed, and hang in the air after being closed Load Capacity: Maximum load capacity of normally open port: DC 0-30V/10A, AC 0-250V/10A Maximum load capacity of normally closed ports: DC 0-28V/10A, AC 0-125V/10A Package List: 1 x Time Delay Relay Note: Function 1‑8 starts automatically when it is powered on. Function 9‑18 needs a high‑level pulse signal (high‑level duration is not less than 20ms, the same below) to trigger the start, and function 19‑20 needs a continuous high level.
