8 Low Current Dc Control Ac Solid State Relay Module Low Level Trigger 5V/12V/24V (Optional)
Specificatii:
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
