Features: Input Power: 5V DC (160MA) 5V solid state relay 240V 2A, the output with a resistive fuse 240V 2A. Size: 2 Way: 55 * 33 * 25 (L * W * H) 4 Way: 57 * 55 * 25 (L * W * H) 8 Way: 106 * 56 * 25 (L * W * H) The Input Control Signal Voltage: High Level Module: (0-2.5V state low level relay ON) (3.3-5V state high level relay OFF) Low Level Module: (0-2.5V state low level relay OFF) (3.3-5V state high level relay ON) There are 2.54CM pin and blue KF301 terminal control line is more convenient. Input Section: DC +: Connect the power supply positive (according to the relay voltage) DC-: Connect the power supply negative CH2: 2-channel relay module signal to trigger the end (high level trigger effective) CH4: 4-channel relay module signal to trigger the end (high level trigger effective) CH8: 8-channel relay module signal to trigger the end (high level trigger effective) 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 side voltage or trigger to reach the trigger Voltage, the relay is pul
