                  Structural Features:
                   
                  1. Use Hongfa relay, stable and reliable performance;
                  2. Compatible with two input modes of positive control and negative control;
                  3. Each channel has an LED action indicator for a more intuitive understanding of product performance;
                  4. Each channel adopts optocoupler isolation to enhance anti-interference performance and isolation performance;
                  5. At the same time, the power supply and the "IN" control terminal are independently controlled;
                  6. The module adopts the standard "DIN" rail-type installation design, which is convenient and quick to install, firm and stable.

                  Positive control wiring introduction:
                   
                  1. Power input terminal:
                  VCC is connected to the positive voltage, GND is connected to the negative voltage, and S / S is connected to the negative voltage
                  IN1, IN2 are connected to positive voltage control, IN1 controls KI terminal, IN2 controls K2 terminal
                  2. Control device output:
                  The output terminal is clearly marked with 234, 3 is a common point, 2 is normally open, and 4 is normally closed. K1, K2 means two relays work.
