2 Channel Multi-function Relay Module Delay Self-lock CycleTiming Timer Relay 5V/12V/21V

The user can select one of the following 20 functions by pressing the button and display, and can set and save the function parameters, and also view the parameters of the current function. The time parameter setting is adjustable by 0.1 second at minimum, and the precision is better than 0.01 second. Instructions for setting up can be obtained from your dealer.

Load capacity: Normally open port maximum load capacity: DC 0-30V/10A, AC 0-250V/10A

Normally closed port maximum load capacity: DC 0-28V/10A, AC 0-125V/10A

Function 1-8 is self-starting when it is powered on. Function 9-18 requires a high-level pulse signal (high-level duration is not shorter than 20ms, the same below) triggers the start, and function 19-20 requires a continuous high level.

1. +: DC power supply positive (5V, 12V and 24V modules are available)

2. DC-: DC power supply negative

3. CH1: Input detection interface 1, active high

4. CH2: Input detection interface 2, active high

1. NO1: The relay normally open interface 1, the relay is suspended before the suction, and it is short-circuited with COM1 after the suction.

2. COM1: Relay Common Interface 1

3. NC1: Relay normally closed interface 1, shorted to COM1 before the relay is closed, suspended after suction

4. NO2: The relay normally opens the interface 2, the relay is suspended before the suction, and the short is connected with COM2 after the suction.

5. COM2: Relay Common Interface 2

6. NC2: The relay normally closes the interface 2, and the relay is short-circuited with COM2 before the suction is closed.
