Description: This product features humanized interface design, all interfaces can be directly connected through the terminal lead.There are four fixing bolt holes are provided. Specification: Weight: 118g/4.2oz Common interface load: AC 250V/10A, DC 30V/10A Module Size (L×W×H): 141.5×50×18.5mm/5.6×2×0.7inch Bolt Hole: 3.1 mm; 136×44.5mm (spacing) Voltage: 5V, 12V, 24V (Optional) Module interface: 1. DC+ : connect to the positive pole of the power supply (5V.9V. 2. DC- : connect to the power negative pole 3. In1-in8: according to the setting of each circuit, the corresponding relay can be controlled with high or low level to suck in Relay output terminal: there are 24 wire interfaces, all interfaces can be directly connected to lead, convenient for users to use 1. NO1--NO8: the relay normally opens the interface, and the relay is suspended before it is sucked in, and then it is connected with COM short after it is sucked in; 2. COM1--COM8: relay common interface; 3. NC1--NC8: 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. The high-low level trigger selection of relay 1-8 channels successively; 2. Com and low short connection, the corresponding relay for low level trigger, com and high short connection for high level trigger. Package List: 1× Relay Module
