This 4 Channel Relay Module 12V High and Low Level Trigger Relay Module comes with a max load for output AC 250V 10A, DC 30V 10A.
A trigger current of 20 mA can be used to all kinds of single chip microcomputer IO control triggering, normally opening and closing two work modes.
By switching the trigger level selection terminal to set 3 5V high level or 0 1.
5V low level trigger controlled,Adopting patch piece opto isolator, green power light, red relay status light, strong drive capability, stable performance, and clear work conditions This product is known as the 4 Channel 12V Relay Module, the 12V 4 Channel Relay Module, and the 12V 4 Channel Relay Optocoupler Isolation Module.
Trigger Mode Configuration The module has a trigger level selection terminal for each relay, the trigger level can be individually controlled through the short circuit cap.
The COM side is common, in the middle.
When the LOW L terminal is connected to the common terminal, it is a low level trigger when the HIGH H terminal is connected to the common terminal, it is a high level trigger.
