Application of ZJ6 type intermediate relay

ZJ6 type intermediate relay (hereinafter referred to as relay) is used in AC operation circuits as an auxiliary relay to expand the control circuit. 2 Working principle and structure
2.1 This relay is an electromagnetic valve type instantaneous action relay, installed on a rubberwood base and covered with a plastic shell. The electromagnet of the relay is fixed on the bracket of the contact system, and the mechanical connection between the armature and the contact system relies on the bent plate on the fixed armature and the top plate located at the end of the bent plate. When the armature is engaged, the top plate pushes the contact piece, causing the dynamic contact point to close and the dynamic contact point to disconnect.
2.2 The primary winding of the saturated AC converter in the relay is connected to the secondary circuit of the instrument transformer. The primary winding of the saturated inverter has two windings, which can be connected in series or parallel.
2.3 The coil of the relay passes through a bridge rectifier composed of diodes and is connected to the secondary circuit of a saturated inverter. A capacitor is connected to the saturated inverter circuit to reduce the peak voltage.
2.4 The relay is controlled by the dynamic breaking contacts of other relays, and the dynamic breaking contacts are connected to 7 and 9. If action signal display is required, a DX-11/0.05A signal relay can be connected to terminals 11 and 13, or two DX-11/0.025A signal relays can be connected in parallel. If not needed, short-circuit with a connecting piece.
The 2.5 relay has one set of conversion contacts and one set of high-capacity main conversion contacts.
2.6 In order to eliminate the misoperation of the controlled switch caused by the unreliable closure of the dynamic breaking contact during conversion, the large capacity main contact can be wired as shown in Figure 1.
2.7 The relay is fixed on a vertical panel and can be wired in front or behind.
2.8 The internal wiring of the relay is shown in Figure 2. The outline drawing and installation dimensions are shown in Figure 3.
