4X One 1 Channel 5V Relay Module Board Shield for with Optocoupler Support High and Low Level Trigger

4X One 1 Channel 5V Relay Module Board Shield for with Optocoupler Support High and Low Level Trigger Popis

The module uses authentic quality relay, normally open interfaces, Maximum load: AC 250V / 10A, 30V / 10A;
Use SMD isolation optocoupler, ability to drive, stable performance.Trip 5mA current.
The operating voltage of the module 5V; The module can be high or low by a trigger of the jumper setting.
The fault-tolerant design, even if the command is case sensitive, the relay won't work;
The power indicator (green), the flag of the State of the relay (red)

Interface module:
1. : positive supply (VCC)
2. : power negative (GND)
3. IN: control relay may be high or low level
Relay outputs:
1. NO: normally open relay interface
2. COM: Common interface relays
3. NC: normally closed relay interface
High and low level triggering options:
It is low level trigger when the jumper connects to bottom pin
It is high level trigger when the jumper connects a high pin
