COVVY 2 Channel Relay Module Relay Expansion Board 5V Low Level Triggered 2-way Relay Module for Arduino

Module parameters: 1. Size: 50.5mm (length) * 38.5mm (width) * 18.5 (height) 2. Weight: 31g 3.PCB color: black 4. There are 4 fixing screw holes around the board, the hole diameter is 3.1mm, which is convenient for installation and fixing. 5. The relay uses high quality Songle relay, single pole double throw. a common end, a normally open end, and a normally closed end 6. Optocoupler isolation, good anti-interference 7. 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. 8. VCC is the system power supply, and JD_VCC is the relay power supply. Plug in the jumper cap Electrical parameters: Supply voltage: 5VDC Current: greater than 100mA Load: 250V 10A AC or 30V 10A DC Wiring instructions: VCC: system power supply positive GND: system power supply negative IN1--IN2: Relay Control Port (Do not reverse, causing the module to burn out and we will not return it.) Package Include: 2-channel 5V Relay Module
