Everyone loves Relay :) It offers control of higher voltage and current from low signal controller e.g.: Arduino :) You can control AC appliances from Arduino via Relay in between.

This is 4-Channel Solid-State Relay Module, it is Arduino compatible. Solid-State Relay is some what similar to that of a mechanical relay & the difference is that, there is no moving contact in a Solid-State Relay. Here we make use of Phototriac coupler to turn it ON and OFF. It finds its application in AC circuits as a TRIAC has got only limited applications in DC. And with that, this relay is suitable to control AC load, not for DC load.

Solid state relays do have several advantages over mechanical relays. One such advantage is that they can be switched by a much lower voltage and at a much lower current than most mechanical relays. Also, because there’s no moving contacts, solid state relays can be switched much faster and for much longer periods without wearing out.

Features:

  • 4-Channel Solid-State Relay
  • Rated output load: 100V ~ 240V AC (50Hz/ 60Hz) 2A per channel
  • Rated input power: 5V, 160mA (all channels ON)
  • Triggered at Low level (or Active Low)
  • Separate LEDs showing status of each Solid-State Relay
  • Input control signal:
    • Low Signal (Solid-State Relay ON / CLOSE), 0V- 2V or GND
    • High Signal (Solid-State Relay OFF / OPEN), 3.3V - 5.0V or leave it floating
  • Dimension: 57mm x 55mm x 25mm
  • Offer two types of input control terminals: Header pin and Terminal Block

Module interface:  (Input)

  • DC+: connect the power supply positive (relay voltage power supply), minimum 5V, maximum 20V.
  • DC-: the cathode of a power supply 
  • CH1: 1 relay module signal trigger end (low level trigger effective) 
  • CH2: 2 relay module signal trigger end (low level trigger effective) 
  • CH3: 3 relay module signal trigger end (low level trigger effective) 
  • CH4: 4 relay module signal trigger end (low level trigger effective)

Packing List:

  • 1 x 4 Channels Solid State Relay Module(Low Trigger)

Does the board have snubber to reduce inrush current? ( Kamal, 02/09/2019 )
Hi, sorry we don't have that.
