This relay module is 12V active low, and each one needs 15-20mA driver current.
Uses two 8-channel ULN2803APG darlington arrays chip to control relay module.
It is a 16-channel relay interface board, which can be controlled directly by a wide range of microcontrollers such as Arduino, AVR, PIC, ARM, PLC, etc.
It is also able to control various appliances and other equipments with large current.
Relay output maximum contact is AC250V 10A and DC30V 10A.
Standard interface can be directly connected with microcontrollers.
The working status indicator lights are conducive to the safe use.
Widely used for all MCU control, industrial sector, PLC control, smart home control.
