2. Action principle and structural characteristics
2.1 Action principle
The action of a relay is based on electromagnetic principles. A permanent magnet is installed between the iron core and the yoke. After the relay is activated, if the power supply to the operating coil is cut off, the relay relies on the magnetic force of the permanent magnet to keep the armature in the holding position, and the contacts and signal signs remain in working condition; When a short reset voltage is applied to the reset coil, the relay returns to the released state.
2.2 Structural Features
2.2.1 Relays are embedded (Q-type) or without status.
The internal wiring diagram of relay 2.2.2 is shown in Figure 1.
2.2.3 The appearance and installation dimensions of the relay are shown in Figure 2.

3 Technical data
3.1 The rated voltage of the reset coil is 36V.
3.2 The operating current value of the attraction coil shall not exceed 90% of the rated value, and the operating voltage value of the attraction coil shall not exceed 70% of the rated value.
3.3 Power consumption: Voltage type relays consume 2W at rated voltage, while current type relays consume 0.15W at rated voltage.
3.4 Thermal stability: Voltage type relays can withstand 110% of the rated voltage for a long time; Current type relays can withstand 400% of the rated current for a long time.
3.5 Contact breaking ability: When the current is not greater than 2A and the voltage is not greater than 250V, the DC inductive load that can be disconnected (time constant not greater than 5H10-3S) is 50W.
3.6 Dielectric strength: The conductive parts and the yoke can withstand an AC voltage of 50Hz and 2kV for 1 minute.
The rated current (or voltage) of the 3.7 relay and the relevant parameters of the attraction coil are listed in Table 1.
