DZ-10,DZ-15,DZ-16 series intermediate relayDetailed product description：

1 Purpose

DZ-10, DZ-15, DZ-16 series intermediate relays are used as auxiliary relays in various protection circuits to increase the number or capacity of contacts of the main protection relay.

Overview of Structure 2
This series of relays is an electromagnetic pull in instantaneous action relay.
The "mountain" shaped magnetic conductor is composed of a magnetic yoke plate and a cylindrical iron core, with a coil mounted on the iron core. The flat armature is hinged with a bronze thin bent plate and a magnetic yoke plate.
The dynamic and static contact systems are respectively fixed on the armature and magnetic yoke. When voltage is applied to both ends of the coil, the armature moves towards the suction position and changes the contact state of the contacts (such as closing the dynamic contact). After removing the voltage (or reducing the voltage to the return voltage), the armature returns to its original position under the reaction force of the tension spring and contact piece, and the contact returns to its normal state (such as closing the dynamic breaking contact).
The DZ-15 intermediate relay has two sets of dynamic contacts and two sets of dynamic contacts.
The DZ-16 intermediate relay has three sets of movable contacts and one set of movable contacts.
The DZ-17 intermediate relay has four sets of dynamic contact points.
The relay is suitable for wiring in front of or behind the board. The internal wiring of the relay is shown in Figure 1:
