  • Jzxc H18 Rectifier Slow Release Relay - China

    price: 398.00 Dollar US$

    Product Usage The JZXC-H18 rectifier slow release relay is used as a filament supervisory relay in the electric centralized lighting circuit.

    Installation Precautions 1 - When installing the relay, make sure that the insulation interval between the sockets is intact, the socket hanging spring is intact, and the socket identification pin is in the correct position and should not be missing.

    2 - Pay attention to the relative position between the relay and the socket when plugging in the relay to avoid damage to the relay or socket during plugging.

    3 - When repairing and replacing the relay, first remove the fixed relay spring, and then pull out the relay.

    Do not use excessive force or shake left and right when pulling it out, as it may damage the relay or socket.

    Applicable environment a) Ambient temperature: -40℃~+60℃; b) Relative humidity: not more than 90% (temperature +25℃); c) Air pressure: not less than 70kPa (equivalent to an altitude below 3000m); d) Vibration: the vibration frequency is not more than 15Hz, and the amplitude is not more than 0.45mm; e) Working position: horizontal; f) There should be no harmful gas causing explosion hazard around, and good dust-proof measures should be taken.

    Product electrical life The relay contact is connected to DC24V1A resistive load; its electrical life is 1×106 times Structural characteristics The electromagnetic system includes coils, iron cores, irons and armatures.

    The coil is installed horizontally on the iron core, and is divided into a front coil and a back coil.

    It is mainly to install a half-wave or full-wave rectifier circuit composed of diodes above the contact group.

    The use of dual coils is to enhance the flexibility and flexibility of the control circuit, which can be controlled by a single coil or a series of double coils according to the circuit needs.

    The armature is fixed on the blade of the armature by the butterfly-shaped steel wire, and it moves flexibly.

    There is a heavy hammer in the transmission part of the armature to ensure that the relay armature returns reliably by gravity.

    The number of weights installed is determined by the structure of the relay contact system, and should be able to ensure the reliable release of the relay.

    A stop piece is installed at the closed position of the armature and the iron core to ensure the minimum air gap of the magnetic circuit of the relay, prevent the ferromagnetic parts of the magnetic circuit from magnetizing, and ensure that the relay falls reliably.

    The iron core, vehicle iron and armature of the relay are made of electromagnetic pure iron, which has high magnetic permeability and small remanence.

    Product characteristics Mechanical characteristics Number of contact groups: 4QH; Identification pin number: 13, 53; Contact gap: not less than 1.3mm; Pallet gap: not less than 0.35mm; Contact pressure: the dynamic contact point is not less than 250mN; the dynamic disconnection point is not less than 150mN; Contact uniformity error: not more than 0.20mm.

    Electrical characteristics Rated value: AC150MA Magnetizing value: AC400Ma Release value: not less than AC40Ma Working value: not less than AC100ma Coil resistance: 9 (1±10%) Q×2 The coils are connected in series, connect 1, 4, use 5, 6; Time characteristics Release time: not less than 0.15 seconds when AC50ma Product barcode The barcode of the Relay Company is pasted on the armature, and the barcode of the Ministry of Railways is pasted on the external device.

    When the product has quality problems or the user has doubts about the product quality, the user should consult the digital code of the bar code, and timely feedback to the company so that the manufacturer can obtain the product information in the first time and realize product quality tracking and after-sales service.
