2 Road 5v Low Level Solid State Relay Module with Fuse SSR 250V 2A Fuse
1. 5V solid state relay 240V 2A, the output with a resistive fuse 240V 2A.
2. Size: 55 * 33 * 25 (L * W * H) Net weight: 21.5g
3. The input power: 5V DC (160MA)
4. The input control signal voltage:
(0-2.5V state low-level relay ON)
(3.3-5V state high level relay OFF)
5. Blue KF301 terminal connected to the control line is more convenient.
DC +: Connect the positive pole of the power supply (according to the relay voltage)
DC-: Connect the negative pole of the power supply
CH1: 1 relay module signal trigger side (low level trigger active)
CH2: 2-way relay module signal trigger side (low-level trigger is valid)
High and low meaning:
High-level trigger refers to the signal trigger side (IN) and the negative power supply has a positive voltage between the positive and the power supply is usually connected to the trigger side of a trigger, when the trigger voltage or trigger a positive trigger Voltage, the relay is pull.
Low-level trigger refers to the voltage between the signal trigger terminal and the negative terminal of the power supply is OV, or the voltage of the trigger terminal is lower than the voltage of the positive pole of the power supply. When the voltage is low enough to trigger, the relay is pulled in, The negative side of the power supply is connected to the trigger side of a trigger, so that the relay is pull.
