12V 4 Channel Relay Module High And Low Level Trigger With Opto Isolation
4 Channel Relay Module 12V High and Low-Level Trigger Relay Module. 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. Tags, 4 Channel 12V Relay Module, 12V 4-Channel Relay Module, 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.
