This 5V relay module operates in high-level trigger mode and is ideal for controlling appliances or for microcontroller development boards. It can handle 5V to 12V TTL control signals and can control both DC and AC signals, including 220V AC loads.

The relay has both normally open and normally closed contacts, with an LED power indicator. When activated, the control light turns on, and it turns off when disconnected. The module includes a transistor to drive the relay coils and features a pull-down circuit on the control pins to prevent malfunctions.

Features:

1) Safe operation: Low current can control higher current in power and high-voltage systems.

2) 2-channel high voltage output supports single-channel control.

3) Can control a wide range of voltages.

4) Capable of handling high current loads, up to 240V and 10A.

5) Equipped with both normally-open (NO) and normally-closed (NC) contacts.

Package includes:

- 1pc x 5V Relay 1 Channel Relay Module
