5V Optocoupler Isolation Relay Module 5V 8 Channels Relay Module High and Low Triggering Optocoupler Isolation Relay Module PLC Signal Amplifier Board

Description:

This 5V Optocoupler Isolation Relay Module is compliant with international safety standards, control and load areas isolation trenches it has a single relay genuine. The inputs of the 8 Channel 5V Optocoupler Isolation Relay Module are isolated to protect any delicate control circuitry. 5V Optocoupler Isolation Relay Module can be used as a single chip module for appliance control and works with both DC or AC signals where you can control the 220V AC load. This 5V Optocoupler Isolation Relay Module comes with a Guide rail on its backside so we can adjust the module to a superior location.

Note: On the high-level and low-level-triggered mode, those who do not understand, have a look

• High-level trigger refers to the signal voltage between input and trigger and can be understood as a signal input with VCC cathode short-circuit triggered away.
• Low-level trigger refers to the signal voltage between the input terminal and Earth OV trigger, which can be understood as a signal input terminal and the GND negative electrode short circuit triggered is a way 8-channel relay module connection.
