Module interface:
1. DC+: Connect to the positive terminal of the power supply
2. DC-: Connect to the negative terminal of the power supply
3. In1-in8: Depending on the setting of each circuit, the corresponding relay can be controlled with a high or low level for activation.
Relay Output Terminal: There are 24 wired interfaces; all interfaces can be directly connected to the wire, convenient for users.
1. NO1--NO8: The relay normally opens the interface and is suspended before activation, then connected to COM shortly after activation;
2. COM1--COM8: Common relay interface;
3. NC1-NC8: Normally closed relay interface. The relay is shorted to COM before activation and suspended after activation.
High and Low Level Trigger Selection Terminal:
1. S1-S8 is the high-low level trigger selection for relays 1 through 8 channels successively;
2. COM and low connection short, the corresponding relay for the low-level trigger, COM and high connection short for the high-level trigger.
