1-Channel DC 3V Relay Module High Level Isolated Driver Control Board for Arduino Raspberry Pi

Description:

• Size: 70mm X17mm X20mm (LxWxH)
• Main chip: EL817, SRD-DC03V-SL-C
• Work voltage: DC 3V/3.3V
• Control 10A 250VAC, 10A 30VDC load

Features:

• Instructions with the signal output;
• Signal input port can connect microcontroller IO port, high level signal
• Double power selection design anti-interference ability is strong, photoelectric isolation protection of high reliability
• Current wide detection range:DC0-25V input
• A diode current protection
• Response time is less than 20 milliseconds
• Relay long life can absorb 100000 times continuously
• External connection use spinning crimping terminal, make connection firmer
• With fixed installation hole, convenient installation

Power interface:

• VCC: Connect to the positive pole of the power supply (3.3V)
• GND: Connect to the negative pole of the power supply
• IN: high level control relay pull-in

Load interface:

• NO: Normally open interface of the relay, the relay is suspended before pull-in, and shorted to COM after pull-in
• COM: Relay common interface
• NC: Normally closed interface of the relay, the relay is short-circuited with COM before pull-in, and hangs up after pull-in
