Product Description

Relay Board, Keenso Relay Module 4 Channel with Optocoupler Low Level Trigger Expansion Board for Arduino 5V/12V/24V(5V)

Features: Adopt patch photocoupler isolation, strong driving ability, stable performance. Trigger current is 5mA. Module operating voltage is 5V,12V,24V for choice. Each path of the module can be triggered by the high level or low level through a jumper setting. Specification:

Weight: 60g/2.1oz
Common interface load: AC 250V/10A, DC 30V/10A
Module Size (L*W*H): 73*50*18.5mm/2.9*2*0.7inch
Bolt Hole: 3.1 mm; 67*44.5mm (spacing)
Voltage: 5V, 12V, 24V (Optional)

Package List:

1 x 4 Channel Relay Module

Module interface:

DC + : connected to the positive pole of power supply (voltage is required for relay, 5V, 12V and 24V for choice)
DC- : connect to the power negative pole.
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

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.
Common interface of relay COM1--COM4.
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:

S 1-S4 is the high-low level trigger selection of relay 1-4 channels successively;
Com and low short connection, the corresponding relay for low level trigger, com and high short connection for high level trigger.
