1 channel 12V 30A Relay Control Board Module with Optocoupler

This 1 channel 12V 30A relay control board module with optocoupler modules is compliant with international safety standards, control and load areas isolation trenches it has a single relay a genuine. The inputs of 1 Channel 12V 30A Relay Module are isolated to protect any delicate control circuitry. It can be used as a single chip module for appliance control and work with both DC or AC signals where you can control the 220V AC load. Note: On the high level and low level-triggered mode, friends who do not understand, have a look High-level trigger refers to the signal voltage between input and trigger, can be understood as a signal input with VCC cathode short-circuit triggered a way; Low-level trigger refers to the signal voltage between the input terminal and Earth OV trigger, can be understood as a signal input terminal and the GND negative electrode short circuit triggered isa way 1-channel relay module connection. Features : High impedance controller pin Pull-down circuit for the avoidance of malfunction One normally closed contact and one normally open contact Triode drive, increasing relay coil Power supply indicator lamp Control indicator lamp With 4 fixed screw holes, hole diameter 3.1mm, convenient installation, and fixation Package Include : 1 x 1 channel 12V 30A relay control board module with optocoupler Specifications :- Channel 1 Trigger Voltage (VDC) 12 Switching Voltage (VAC) 250@30A Switching Voltage (VDC) 30@30A * Product Images are shown for illustrative purposes only and may differ from actual product.
