DC- : connect to the power negative pole. 3. IN1-IN4: according to the setting of each circuit, the corresponding relay can be controlled with high or low level to suck in. Relay output terminal: with 12 lines of interfaces, all interfaces can be directly connected to lead, convenient for users to use 1. NO1--NO4: the relay normally opens the interface, and the relay is suspended before it is sucked in, and is connected with COM after it is sucked in. 2. Common interface of relay COM1--COM4. 3. NC1--NC4: relay normally closed interface. The relay is short connected with COM before it is sucked in and suspended after it is sucked in. High and low level trigger selection terminal: 1. S1-S4 is the high-low level trigger selection of relay 1-4 channels successively; 2. Com and low short connection, the corresponding relay for low level trigger, com and high short connection for high level trigger.
