DZS-100Q series intermediate relayDetailed product description：

Application of DZS-100Q series intermediate relay
The DZS-100Q series intermediate relay is used as an auxiliary relay in DC operated protection circuits to increase the number or capacity of contacts of the main protection relay. DZS-115Q and DZS-117Q are delay action relays, DZS-127Q and DZS-136Q are delay voltage action and current protection relays, and DZS-145Q is a delay return relay.

2 Structure and principle
2.1 The DZS-100Q series intermediate relay adopts embedded installation, and the main body is a plug-in structure.
The main body of the DZS-100Q series intermediate relay is the same as that of the DZS-100 series intermediate relay.
2.3 The DZS-100Q series relay is a pull in electromagnetic relay, with the coil of the relay mounted on a cylindrical iron core of a mountain shaped magnetic conductor. The DZS-115Q and 117Q models have only one working winding (voltage winding), while the DZS-127Q and 136Q models have one working winding (voltage winding) and two holding windings (current winding). Damping rings are simultaneously installed on the cylindrical iron core above or below the coil, thereby obtaining delayed action or delayed return of the relay.
The dynamic and static contact systems of the 2.4 relay are respectively fixed on the armature and yoke of the magnetic conductor. The armature and yoke are hinged with support pillars, and the relay is returned and in the open position by the action of a tension spring.
The internal wiring of the 2.5 relay is shown in Figure 1.
