DZ-50 series intermediate relayDetailed product description：

Application of DZ-50 series intermediate relay
The DZ-50 series intermediate relay is used in automatic control devices to expand the controlled circuit and improve contact capability.

2 Structure and principle
This relay is an electromagnetic intermediate relay, which operates based on electromagnetic principles and belongs to a type of fast acting relay. It has an attraction coil (AC or DC) installed on a mountain shaped magnet with a movable iron plate on top. When the torque generated by the electromagnetic attraction between the air gaps exceeds the reaction torque, the relay will operate. When the attraction coil is powered off, the movable system will be restored to its original position by the reaction force.
The internal wiring diagram of the relay is shown in Figure 1.



Figure 1 shows the internal wiring diagram as follows: two in one, two in one (220), four in one (040), and four in one (400)
