Jyjxc 135 220 Type Reinforced Contact Relay With Pole - China

price: 398.00 Dollar US$

Product Usage The JYJXC-135/220 type has a pole reinforced contact relay used as a switch control relay in a signal circuit.

Applicable environment The applicable environment of the relay is: a) Ambient temperature: -40℃~+60℃; b) Relative humidity: not more than 90% (temperature +25°C); 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.

Mechanical properties Number of contact groups: 2DF, 2DFJ; Identification pin number: 15, 54; Contact gap: ordinary contact is not less than 4.5mm; reinforced contact is not less than 7mm; Pallet gap: ordinary contact point is not less than 0.35mm; Ordinary contact pressure: the positioning contact is not less than 150mN; the reverse contact is not less than 150mN; Strengthen the contact pressure: the positioning contact is not less than 400mN; the reverse contact is not less than 400mN; Contact uniformity error: between ordinary contacts and ordinary contacts, between ordinary contacts and reinforced contacts, no more than 0.2mm, between reinforced contacts and reinforced contacts, no more than 0.1mm.

Positioning or reverse position holding force is not less than 4N; Electrical characteristics (at 20c) Coil resistance: 135/220Ω Use the coil alone, use 1, 23, 4; Rated value: 24V; Magnetizing value: 64V/64V; Rotation extreme value: forward 10V~16V, reverse 10V~16V; Contact resistance: common contact is not more than 0.05Ω; The strengthened contact is not more than 0.1Ω.

Product function The signal relay is an important element in the interlocking equipment, and it is the main equipment to ensure the safe operation of the system.

The signal relay can control the conversion, lock and unlock the way of the road meeting, and control the opening and closing of the signal machine.

Its reliability, availability, maintainability and the entire sauna line are the keys to the safety of railway transportation and operational services.

Insulation withstand voltage Under the standard atmospheric conditions of the test, the insulation resistance of the relay should not be less than 100MQ.

Under the condition that the air pressure is not lower than 86kPa (equivalent to the altitude below 1000m), the insulation withstand voltage of the relay should be able to withstand AC sine wave 50Hz, 2000V rms voltage, there should be no breakdown flashover after 1min, the voltage when repeating the test Should be 75% of the original test voltage value.

Product electrical life The ordinary contact of the relay is connected to DC24V1A resistive load; the strengthened contact is connected to DC220V7.5A, 0.05H inductive load, and its electrical life is 1×105 - Installation precautions 1 - When installing the relay, make sure that the perfect interval in the middle of the socket is intact, the socket hanging spring is intact, and that 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 same set 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.
