1 Channel Relay Module 5v Shield for Arduino AVR ARM PIC DSP

Description:

• Brand new 5V relay module
• Microcontroller development board can be used as
• modules, can be used as appliance control
• 5V-12V control signal of the TTL
• Control DC or AC signals can control the 220V AC load.
• There is a normally open and one normally closed contact Power LED
  Controlled light, pull off, off off
• Increased transistor drive a relay coil, the control pin high impedance.
• Control pins have pull-down circuit, to prevent floating relay malfunction
