Product Usage The JWXC-2.3 type infinite relay is used as a DC track relay in the signal circuit. Features 1. The relay is a heavy elastic DC electromagnetic relay, which uses the principle of "constant gravity" to force the moving and closing contacts to open when the coil is de-energized. 2. It adopts silver-silver cadmium oxide contact, which has the characteristics of strong anti-adhesion and low contact resistance. 3. The magnetic circuit adopts electromagnetic pure iron material with small residual, and installs the stop piece at the closed position of the armature and the iron core to ensure the minimum air gap of the magnetic circuit, prevent the magnetization of the ferromagnetic parts of the magnetic circuit, and ensure the reliable fall of the relay. 4. The contact system is composed of ordinary contacts, and there are four groups of ordinary contacts for switching on and off. 5.The rated current of the relay is 280mA DC. 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 structure Infinite relay is the typical structure of Ax series relay, which is composed of electromagnetic system and contact system. The electromagnetic system includes coil, iron core, choke and armature. The coil is installed horizontally on the iron core, and is divided into a front coil and a back coil. 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 iron by a butterfly-shaped steel wire, which is flexible in movement. 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, choke iron and armature of the relay are made of electromagnetic pure iron, which has high magnetic permeability and small remanence. Installation method
