This 5V 16-Channel Relay interface board can be controlled directly by Micro-controller (Arduino, 8051, AVR, PIC, DSP, ARM, MSP430, TTL logic). Each relay requires 15-20mA Driver Current and features indication LED for Relay output status. The module supports all SCM Drive and can be used as a microcontroller development board module or for appliance control and PLC extended output.
The module uses top-quality isolation optocouplers for strong anti-jamming ability and stable performance. Each relay common terminal "COM" is independent, allowing user-friendly access to different signals. The module can handle full on/off for each road and is equipped with motion lights. All interfaces can be easily connected through terminal leads.
Instructions:
- The power supply should be DC 5V within the specified range.
- Avoid reversing the power supply.
- Ensure the load power has a margin for the relay load to prevent impact on product life.
Applications:
Can be used as a microcontroller development board, home appliance control, or PLC expansion output.
