HALJIA 3PCS 2 Channel Relay Module - 5V Relay Board Expansion Board Universal Development Board Accessories with Optocoupler Compatible with Raspberry Pi Arduino PIC AVR MCU DSP ARM TTL Logic

• The relay uses high quality material, single pole and double throw. a common end, a normally open end, and a normally closed end.
• Optocoupler isolation, good anti-interference.
• There are 4 fixing screw holes around the board, which is convenient for installation and fixing.
• Low level pull-in, high level release. The status indicator is on when the inverter is closed, and the status indicator is off when released.
• VCC is the system power supply, and JD_VCC is the relay power supply. The default 5V relay, plug in the jumper cap.
