1-Way Relay Driver Module with LED Indicator Microcontroller Compatible PLC MCU Control Board 5V

1. This module complies with safety standards, and there is an isolation slot between the control area and the load area.
2. It uses high-quality relays, with power supply and relay action indication, bright when closed, and not bright when disconnected.
3. When there is a signal at the signal input end, the common end and the normally open end be connected.
4. It can be used as a single-chip microcomputer development board or PLC module, and can be used for home appliance control.
5. It can control DC or AC signals and can control 220V AC loads. It is more convenient to connect the blue KF301 terminal to the control line.

Item Type:1-way Relay Module
Power Indicator:Green
Wiring principle:High level trigger refers to the trigger mode when there is voltage between the signal input terminal and the ground, which can be understood as a trigger mode when the signal input terminal and the positive pole of VCC are short-circuited. Low level trigger refers to the trigger mode when the voltage between the signal input terminal and the ground is 0V, which can be understood as a trigger mode when the signal input terminal and the negative pole of GND are short-circuited.
Due to different batches,there may be differences in product appearance and printed text, which not affect use
