The trigger is usually realized by connecting power positive end to the signal trigger end. When the trigger end has positive voltage or voltage reaches the trigger point, relay is closed. Low level trigger refers to a 0V between the signal trigger end and the power negative pole, or the voltage of the trigger end is lower than that of the power positive pole, which reaches the level of trigger point, the relay is closed. The trigger is usually realized by connecting power negative end to the signal trigger end.

DC-: Connect the power negative pole. 3. IN1-IN8: According to the setting of each way, the corresponding relay-operating can be controlled by high or low level. Relay output: there is a 24 wire interface, all interfaces can be directly connected to lead to facilitate user use. 1. NO1--NO8: Relay normal open, the relay suspends before pulling in, and then short-connect with the COM. 2. COM1--COM8: Relay common interface 3. NC1--NC8: Relay normal close, short connected with COM before pulling inand suspended after pulling in. High and low level trigger option: 1. S1-S8 is the high level trigger selection of relay 1 Channel - 8 Channel. 2. When COM is short connected with LOW, the corresponding relay is LOW level trigger, while when COM is short connected with high end is high level trigger. Package Included: 1 x 8 Channel 24V Relay Module
