In the realm of electrical engineering, China continues to make significant strides with the introduction of its groundbreaking 4Pin Relay. This cutting-edge component is poised to redefine reliability, efficiency, and overall performance in various electrical applications.

The 4 and 5 pins are all single-pack relays, that is, there is only one coil and can only control one channel.

①Normally open contact: Pins 85 and 86 are internally connected to the coil, and externally connected to the control terminal, such as switches, output control signals,

Electromagnetic relay: an electrical relay that works by using the suction effect of the current in the input circuit between the electromagnet core and the armature.
