8 Channel Optocoupler Relay Module Board High & Low Trigger

Features:
Adopt patch photocoupler isolation, strong driving ability, stable performance. Trigger current is 5mA.
Module operating voltage is 5V,12V,24V for choice.
Each route of the module can be triggered by the high level or low level through a jumper setting.
Fault-tolerant design,even if the control line breaks,the relay will not move.
Power indicator light (green), 8-way relay state indicator light (red).
Humanized interface design, all interfaces can be directly connected through the terminal lead.
Four fixing bolt holes are provided.
Specification:
Weight: 118g/4.2oz
Common interface load: AC 250V/10A, DC 30V/10A
Module Size (L x W x H): 141.5 x 50 x 18.5mm/5.6 x 2 x 0.7inch
Bolt Hole: 3.1 mm; 136 x 44.5mm (spacing)
Voltage: 5V, 12V, 24V (Optional)
Module interface:
1. DC+ : connect to the positive pole of the power supply
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. S1-S8 is 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.
