8-kanaals relaismodule Relaiskaart met optocoupler Low Level Trigger-uitbreidingskaart voor Arduino 5V/12V/24V (12V) Relais

8 Channel Relay Module Relay Board with Optocoupler Low Level Trigger Expansion Board for Arduino 5V/12V/24V

Features:
Adopt patch photocoupler isolation, strong driving ability, stable performance. Each path 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.

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. 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.
