Module Interface:

1. DC+: Connect the positive pole of the power supply

2. DC-: connected to the negative pole of the power supply

3. IN1-IN8: According to the setting of each way, the corresponding relay can be controlled by high or low level.

Relay output: 24-line interface, all interfaces can be directly connected to facilitate user access.

1. NO1--NO8: The relay normally open interface, the relay is suspended before the suction, and it is short-circuited with COM after the suction.

2. COM1--COM8 relay common interface

3. NC1--NC8: The relay normally closes the interface, and the relay is shorted to COM before the suction is closed.

High and low trigger selection:

1.> S1-S8 are the high and low level trigger selections of relays 1 to 8 in sequence;

2.> com is shorted with low, the corresponding relay is triggered by low level, and when com is shorted with high terminal, it is triggered by high level.

Technical Parameters:

Relay version: 5v

Quiescent Current: 5mA

Maximum current:190mA

Trigger current: 2-4mA

Low trigger voltage: 0-1.5V

High trigger voltage: 2.5-5V.
