Product Overview
Description:
This is a 5V 1-Channel Relay module, it allows the Arduino to control high power sources (see ratings below).
- Trigger mode: high level
- 5V relay module
- Can be used for microcontroller development board module or home appliance control
- 5V - 12V TTL control signal
- Can control DC or AC signal, also 220V AC load
- Normally open(NO) / closed(NC) contact
- Power indicator
- Controlled lights bright when pull and not shine when disconnect
- Increase the transistor drive relay coils, control pins high impedance
- Control pins have pull down circuit to prevent malfunction of relay vacant
