220V 8-Channel Optocoupler Isolation Module/220V Detection Module/AC Detection Module/Card Guide Enhanced Version

220V 8-channel optocoupler isolation module/220V detection module/AC detection module/card guide enhanced version

Description:

The new enhanced version of the 8-channel 220V optocoupler isolation module has greatly improved the driving ability compared with the previous generation module. It adopts NPN transistor output. The saturated conduction current can reach 100-300MA. It can be connected to any single-chip or PLC.

Effect:

It can be used to detect the presence of 220V alternating current. When 220V is connected, the photocoupler is connected to the ground, and if there is no 220V, it is not connected.

The output high and low level can be directly connected to the IO port of the MCU for detection. The power supply can be 3-24V, or it can be connected to the PLC to be compatible with all PLC inputs. The card rail can be used with the PLC bracket to card the rail.

Safety Warning:

When in use, after the module is powered on, do not touch any components in the white wire frame on the board, because it is high voltage. Please pay attention to the safety of electricity.
