1. Application of DS-110/120Q series time relay
DS-Q series time relays (hereinafter referred to as relays) are used as auxiliary components in various protection and automatic circuits, enabling adjustable delay in the action of controlled components.

2. Structure and operating principle of DS-110/120Q series time relay
2.1 The relay adopts embedded installation, and the main body is a plug-in structure.
2.2 The main body of the DS-Q series time relay is the same as that of the DS series time relay.
2.3 The relay is a suction type electromagnetic relay with a delay mechanism.
2.4 The relay has one instantaneous conversion contact and one delayed dynamic closing contact. For DS-114, 115, 116, 124, 125, 126Q type relays, an additional delayed sliding main contact is required.
The coil of the 2.5 relay is fixed inside the U-shaped magnet. When a voltage is applied to both ends of the coil, the rotor (iron core) is sucked in and instantly makes contact
Point half closing, the dynamic breaking contact opens, and at the same time, the delay mechanism starts to move. Under the action of the tension spring of the delay mechanism, after a certain period of time (set time), the main contact of the delayed dynamic closing is closed (for DS-114, 115, 116, 124, 125, 126Q relays, the sliding main contact is closed first, and then the final dynamic closing main contact is closed after a certain period of time). The period from the moment the voltage is applied to the electromagnetic coil to the time when the main contact of the delayed closing can be adjusted by changing the position of the static contact, and indicated directly on the scale of the relay by the pointer. When the coil is powered off, the chirp and delay mechanism instantly return to their original positions under the action of the tower spring.
The internal wiring diagram of the 2.6 relay is shown in Figure 1.
The appearance and installation dimensions of the 2.7 relay are shown in Figure 2.
