Description
This relay module is 5V/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 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.
Features:
- Control signal voltage range: The trigger signal is low level 0-2V.
- Adopting high quality isolated optocoupler, it has strong anti-interference ability and stable performance, the trigger current only needs 3mA.
- 16 channels can be turned on/off at will, or any way.
- Output form: Directly connected to AC 220V 10A or DC30V 10A load.
- Each relay common terminal COM is independent, which is convenient for users to access different signals. Each relay has a normally closed and normally open port.
- Each relay has an action indicator, which is illuminated and turned off.
- The interface design is user-friendly, and all interfaces can be directly connected through the terminal block, which is very convenient.
- Can be used as a microcontroller development board, can be used as home appliance control, can also be used as PLC expansion output.
- The power supply cannot be reversed.
- The load power should have a certain margin for the relay load. Avoid high power (about 2000W) and work for a long time, which will have a certain impact on product life.
- There are 4 fixing bolt holes for easy installation.
