JOSEF voltage relay DY-34/60CG undervoltage type 15-100V with two pairs of normally closed contacts

Description :

　　One purpose

　　DY series voltage relays are used in relay protection circuits as action components for overvoltage protection or low-voltage lockout.

　　working principle

　　The relay is electromagnetic and operates instantaneously. The magnetic system has two coils, with the coil heads connected to the base terminals. Users can connect the coils in series or parallel as needed, thus doubling the setting range of the relay.

　　The scale value and rated value of the relay are sufficient when the coils are connected in parallel (in V units). Rotate the pointer on the dial to change the reaction torque of the balance spring, thereby changing the action value of the relay.

　　Relay action: For overvoltage relays, when the voltage rises to or exceeds the set value, the relay will act, closing the dynamic contact and disconnecting the dynamic contact. When the voltage drops to 0.8 times the set value, the relay returns, the dynamic contact opens, and the dynamic contact closes. For low-voltage relays, when the voltage drops to the set voltage, the relay acts, the dynamic contact opens, and the dynamic contact closes

　　II Technical Specifications

　　DY-32/60C and DY-34/60C specifications are long-term thermal stable (with built-in series capacitors) voltage relays.

　　● Relay scale limit error: not greater than 6%.

　　● Variation of action value: not greater than 6%.

　　The return coefficient of voltage relays DY-31, 32, 33, and 34 shall not be less than 0.8; DY-35、 The return coefficient of low voltage relays 36, 37, and 38 shall not exceed 1.25.

　　Action Time

　　For overvoltage relays

　　At 1.1 times the action value, the action time should not exceed 0.12s; at 2 times the action value, the action time should not exceed 0.04s.

　　For low-voltage relays

　　When the working voltage of the relay is 0.5 times the set voltage, the action time shall not exceed 0.15 seconds.

　　● Overvoltage capability: When the coils are connected in parallel, the voltage should be uniformly raised from zero to 1.05-2.2 times the set voltage at the minimum setting value. Within this range, the relay should not have any vibration that would cause the dynamic contact to not work. After this test, the relay should still meet the technical requirements.

　　● Overvoltage: When the setting value is increased by 1.75 times or higher, the dynamic contact of the relay should close without shaking.

　　When there are no external collisions or vibrations. When the working voltage at each setting position (excluding point *) of the overvoltage relay is 0.6 times the setting value, its dynamic breaking contact should reliably close the circuit.

　　When the working voltage of a low-voltage relay is 0.6 times the set voltage or lower, its dynamic breaking contact should close without shaking.

　　When there is no external collision or vibration, the working voltage at each setting position of the low-voltage relay should not be less than 1.5 times the setting voltage, and its dynamic contact should reliably close the circuit.

　　Under the action voltage and return voltage; The movable system of the relay should not be stuck in the middle position.

　　When the relative humidity of the surrounding air is not greater than 85%, the insulation resistance of the relay circuit to the shell (non-conductive metal part on the shell) should not be less than 300M Ω when measured with a 500V megohmmeter.

　　The insulation of the conductive part of the relay to the shell (non-conductive metal part on the shell) can withstand a test of 50Hz AC voltage 2kV for 1 minute.

　　● Contact breaking capacity: When the voltage is not greater than 250V and the current is not greater than 2A, the breaking power of the contact is 50W in a DC circuit with inductive load (time constant not greater than 5 × 10-3s) and 250VA in an AC circuit.

　　Power consumption: At the minimum setting value, the power consumed by the coil of the relay does not exceed 20VA.

　　When the temperature of the surrounding medium is+40 ℃, the relay can operate for a long time under the long-term allowable current and voltage shown in Table 2 and Table 3 without damage to insulation and other electrical components, and the temperature rise of the coil is not greater than 65 ℃.

　　● Lifespan: The relay has an electrical lifespan of 500 times and a mechanical lifespan of 5000 times.
