Product Description

DESCRIPTION:

• This is 8-Channel Solid-State Relay Module, it is Arduino compatible. Solid-State Relay is somewhat like 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:

• 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: 106 mm x 56 mm x 25mm
