1pcs 5v 8 Channel Relay Module 8 Way Solid State Relay Module for Arduino Low Level Trigger

5V solid state relays 240V 2A, output with resistive fuse 240V 2A
Size: 103*53*21mm/4.05*2.08*0.82"
The input power supply: 5V DC (160mA)
The input control signal voltage:(0-2.5V low state relays ON) (3.3-5V state high relay OFF)
2.54cm pin and blue KF301 terminals connected to the control line is more convenient
