2 Channel Relay Shield for Arduino UNO Circuit and PCB layout

2 Channel Relay Shield for Arduino UNO Circuit and PCB layout

2 Channel Relay shield for Arduino UNO can be used in several applications like remote control, on/off AC or Dc load and any circuits which required isolated high current and high voltage. Relay 1 connected to Digital pin D2 and Relay 2 can be controlled through D12 of Arduino PIN. Both relay has optocoupler in input for isolation which protect Arduino from any EMI noise and complete isolation between high volt/current at relay outputs.  Relay shield required separate 12V DC. Two LED indicate the Relay operations. J1,J2 provided In case single supply for relay and Arduino required.

  • Input: 12 VDC @ 84 mA
  • D2 and D12 Arduino connected to Relay inputs
  • Solder PCB Jumper J1 and J2 if Shield and Arduino need common supply
  • High TTL Signal Required to Trigger the Relay
  • Output: Two SPDT relay
  • Relay specification: 5 A @ 230 VAC
  • Trigger level : 2 to 12 VDC
  • Header connector for connecting power and trigger voltage
  • LED on each channel indicates relay status
  • Power Battery Terminal (PBT) for easy relay output connection

  • Maximum Current Load 15Amps
  • Gate Driver Supply 15V DC

 

PWM 2 Amp Solenoid,Valve,Heater Driver Using DRV101

The DRV101 is a low-side power switch employing a pulse-width modulated (PWM) output. Its rugged design is optimized for driving electromechanical devices such as valves, solenoids, relays, actuators, and positioners.The DRV101 is also ideal for driving thermal devices such as heaters and lamps. PWM operation conserves power and reduces heat rise, resulting in higher reliability. In addition, adjustable PWM allows fine control of the power delivered to the load. Time from dc output to PWM output is externally adjustable. The DRV101 can be set to provide a strong initial closure, automatically switching to a soft hold mode for power savings. Duty cycle can be controlled by a resistor, analog voltage, or digital-to-analog converter for versatility. A flag output indicates thermal shutdown and over/under current limit. A wide supply range allows use with a variety of actuators. The DRV101 is available in a 7-lead staggered TO-220 package and a 7-lead surface-mount DDPAK plastic power package. It is specified over the extended industrial temperature range of –40°C to +85°C.

FEATURES
