The power supply voltage of the relay module is DC5V. The maximum output load is AC250V 10A and DC30V 10A. The relay has a standard interface and can be directly connected to the microcontroller, which is convenient for wiring. Package contains 10 male to female DuPont wires. High Level or Low Level Trigger. Pull in at low level and release at high level. The status indicator is on when it is pull in, and it is release when it is released. The 2 channel relay interface board can directly control Arduino, AVR, PIC, ARM, PLC and other single-chip microcomputers, and can also control various high-current electrical appliances and other equipment. Widely used in all MCU control, industrial fields, PLC control, smart home control. Module parameters:
▪Size: 51mm(L)*39mm(W)*18.5mm(H)
▪Single weight: 28g
▪PCB color: black
▪There are 4 fixing screw holes around the board, the hole diameter is 3.1mm, which is convenient for installation and fixing
▪High quality relays. A common end, a normally open end, and a normally closed end.
▪Optocoupler isolation, good anti-interference.
▪Low level pickup, high level release. The status indicator is on when it is engaged, and it is off when it is released.
▪VCC is the system power supply, JD_VCC is the relay power supply. Just plug in the jumper cap.
▪Power supply voltage: 5VDC
▪Current: more than 100mA
▪Load: 250V 10A AC or 30V 10A DC
