- 1-Channel relay module, with photoelectric isolation
- dc or ac signal control, can control 220 v ac load
- 5v relay, low level trigger
- Indication LED’s for Relay output status
- High Quality Atomic Market Product
- Relays are suitable for driving high power electronic devices such as lights, electric fan and air condition. This relay module can be used to control high voltages with a low voltage by connecting to an MCU
- Controls DC or AC signals ? 220V AC load
- Working voltage: 5v;size: 2.0 x 4.3 cm
- With power indicator and signal output indicator
- Working principle: when a high level is given to SIG, the PNP transistor is energized, coil of the relay electrified, normally open contact closed, and the indicator LED lights up; when a low level is given, PNP will be de-energized, the original state is restored ? the normally closed contact closed, and the indicator LED goes out then.
