The 125840-02 relay module is an electronic control device commonly used in automated control circuits. The relay module has a control system and a controlled system. When the input quantity changes to meet the specified requirements, the controlled quantity undergoes a predetermined step change in the electrical output circuit. Generally speaking, a relay has one moving contact and two stationary contacts A and B. When switch K is disconnected, there is no current flowing through the relay circuit. At this time, the moving contact and the stationary contact B are in contact, and the upper part of the circuit is conducting. Static contact A is called a normally open contact (NO) and is usually in the open state. Moving contacts are also known as common contacts (COM). The characteristics of the 125840-02 relay module include the following: high reliability: The relay module is usually composed of electromagnetic coils, contacts, springs, auxiliary circuits, and other parts, and its inherent components determine its long life and high reliability. Isolation: The relay module has good isolation, and through the working principle of electromagnetic induction, it isolates the control signal and the controlled circuit, ensuring the safety and stability of the system. High sensitivity: The input voltage range of the relay module is wide, the driving power is low, and it can be compatible with most logic integrated circuits without the need for buffers or drivers, thus having high sensitivity.
