5V 1-Channel High-Level Trigger Solid State Relay (SSR) Module is an electronic switching device that allows a low-voltage control signal (like from an Arduino or Raspberry Pi) to safely control higher voltage AC or DC loads without mechanical contacts.
Input power: 5V DC (160MA)
1 channel: 25*34*25
Input control signal voltage:
0-2.5V state low level relay ON
3-5V state high level relay OFF
Output resistance fuse 240V 2A.
