  Module Description :

  1 , the module complies with international safety standards , the load control area and regional isolation tank ;

  2, using double-sided FR-4 circuit board design, high-end chip production process ;

  3, using loose music authentic relay control ;

  4, with the relay instructions , pull off, disconnect does not shine ;

  5, the signal input has a low signal , often beginning with a common terminal will be turned on ;

  6 , the relay can control the various devices and the load ;

  7 , 8 and 8 normally open normally closed contact ;

  8 , blue KF301 terminals to the control line is more convenient.

      4 way: 57 * 55 * 25 (long * wide * high)

      8 Way: 106 * 56 * 25 (L * W * H)

  3. input power: 5V DC (160MA)

  4. 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)

  5. 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

  CH1: 1 relay module signal trigger terminal (low level trigger active)

  CH2: 2 relay module signal trigger terminal (low level trigger active)

  CH3: 2 relay module signal trigger terminal (low level trigger active)

  CH4: 2 relay module signal trigger terminal (low level trigger active)

  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 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 terminal 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.

  Electrical parameters:

  Voltage Version Quiescent Current Operating Current Trigger Voltage Trigger Current

   1 channel 5V 0mA 12.5mA 0-2.5V 2mA

   2 5V 0mA 22.5mA 0-2.5V 2mA

   4 5V 0mA 48mA 0-2.5V 2mA

   4 5V 0mA 102mA 0-2.5V 2mA

  product manual:

  1. Module power supply: the power must be DC, the voltage and the relay voltage to match

  2. Wiring method:

  When the trigger side of the signal trigger level, the relay will be connected, the device has electricity and work

  Precautions:

  1. Module power supply: power must be DC, 5V power supply

  2. Module control terminal voltage: This module can only be used to control the AC current, can not control the DC current.
