KNACRO 8-Channel Low Level Trigger Solid State Relay Module DC-DC Load 5A Switch Control Panel Module (DC 12V)

Using FR-4 double-sided circuit boards.
5A high quality solid state relay.
Input and output are using KF128-3.81 Terminal Block, wiring more convenient.
Use SS8050 1.5A high current transistor for switching transistor, quality is more stable.
PCB has four screw holes.

Power supply: 5V DC.
Trigger: LOW trigger
5V: 0-1.5V DC relay switches (ON), 3-5V above the relay off (OFF), Note: 6V unknown state.
12V: 0-4.5V DC relay switches (ON), 5.5-12V above the relay off (OFF),
