BESTEP 2 Channel 24V Relay Module Low Level Trigger Optocoupler Isolation For Auduino

Module parameters: 1. Size: 50.5 x 38.5 x 18.5mm (length x width x 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. Relay with 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, use with the jumper cap Electrical parameters: Supply voltage: 24V 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 the connection, the reverse connection will cause the module to burn out.) Package includes: 1 x Relay Module
