As a nice bonus, it even includes a programmable gain amplifier, up to x16, to help boost up smaller single/differential signals to the full range. We like this ADC because it can run from 2V to 5V power/logic, can measure a large range of signals and it is super easy to use. It is a great general purpose 12-bit converter.

EWALL- 2 Channel Relay Module 5V TTL 220V 10A
close

This relay module is completely designed and manufactured by EWALL. 

The 2 channel 5V relay module provides 2 optically isolated inputs that accept a wide range of voltage, including the 3VDC and 5VDC signals available on the Arduino. This is a great way to switch on or off AC or DC loads using your Arduino.

The relays are single-pole-double-throw (SPDT) and are rated for 10A @ 250VAC. The ground for the relay coils is separate from the ground for the input signals. This, along with the optical isolation, provides a total galvanic isolation between the input and output. The two grounds could be joined together if desired with the included jumper.

The relay coils run on 5VDC, and the module has screw-terminal blocks for sturdy and reusable attachments for the external load. The signal and power inputs run through the male single-row header.

Compares with the traditional mechanical relay, the Solid State Relay (SSR) has many advantages: it has a longer life, with a much higher turn on/off speed and no noise. Besides, it also has better resistance to vibration and mechanical shock, and better moisture proof performance.  
      This Solid State Relay Module is based on Omron G3MB, to control current upto 2A@240VAC, can be widely used in various areas such as computer peripheral interfaces, temperature/speed light adjustment, servo control, petrochemical, medical instrumentations, financial devices, coal, meters, traffic signals, etc.

Features

  • Control Voltage:5V
  • Static Current:0mA
  • Working Current:12.5mA
  • Trigger Voltage:0-1.5V
  • Trigger Current:2mA

Instructions

  • DC+:Connect power positive
  • DC-:Connect power negative
  • CH:Relay module signal trigger end(Low level trigger is effective)
  • Wiring: When the triggered by low voltage, current will get through.
