1 Purpose
The DJ-100 series voltage relay is used in relay protection device circuits as an action component for overvoltage protection or low-voltage lockout.

Overview of Structure 2
The DJ-100 series voltage relay is an electromagnetic instantaneous action. AC voltage is applied to the two coils of the system, and the wiring head is on the terminal of the relay base. With a special connecting piece, the coils can be changed from parallel to series, which can double the setting range of the relay.
The DJ-100 series relay is installed on a vertical panel and can be wired in front of or behind the board. The internal wiring diagram of the relay is shown in Figure 1.

3 Technical data
3.1 Disconnecting capacity of contacts: When the voltage is not greater than 220V and the current is not greater than 2A, it is 50W in DC circuits with inductive loads (time constant T not greater than 5 × 10-3S); in AC circuits (COS Φ=0.4), it is 250VA
3.2 Action time: For overvoltage relays, the action time should not exceed 0.12s at 1.1 times the set value; for overvoltage relays, the action time should not exceed 0.04s at 2 times the set value; and for low-voltage relays, the action time should not exceed 0.15s at 0.5 times the set voltage.
3.3 Insulation strength: The various circuits of the relay should withstand AC 50Hz, voltage 2kV, and a 1-minute test without breakdown or flashover between the exposed non charged metal parts.
The weight of the relay is approximately 1.5kg

The other main technical data of the 3.5 voltage relay are listed in Table 1.
