Jwjxc H125 0 44 Stepless Reinforced Contact Slow Release Rela - China

price: 398.00 Dollar US$

Product Introduction JWJXC-H125/0.44 stepless enhanced contact slow release relay is an important component in interlocking equipment and the main equipment to ensure the safe operation of the system.

The signal relay can control the switching, locking and unlocking of the turnout, and control the opening and Close and so on.

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

The automatic control systems in various fields all use relays.

Relays are widely used in railway signal technology, called signal relays, which are important components in railway signal technology.

It plays an important role no matter as the core component of the relay signal system or as the interface component of the electronic or computer signal system.

The reliability of the relay action directly affects the reliability and safety of the signal system.

Product Usage JW.

JXC-H125/0.44 - The stepless strengthened contact slow release relay is used as a general relay in the signal circuit.

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.

Structural characteristics Mechanical properties Number of contact groups: 2QH, 2QJ, 2H; Identification pin number: 15, 55; Ordinary contact gap: not less than 1.3mm; Strengthen the contact gap: not less than 2.5mm; Ordinary pallet gap: not less than 0.35mm; Reinforce the gap of the support plate: not less than 0.1-0.3mm; Ordinary contact pressure: dynamic closing or positioning contact not less than 150mN; dynamic breaking or reverse position contact not less than 150mN; Strengthen the contact pressure: the dynamic closing or positioning contact is not less than 400mN; the dynamic breaking or reverse position contact is not less than 300mN; Contact uniformity error: not more than 0.20mm.

Electrical characteristics Coil resistance: 125, 0.44 (1±10%) Q, Coil single connection, use 1, 2, 3, 4; Rated value: DC24V, 2A; Magnetizing value: DC48V; Working value: not more than DC12V; Release value: not less than DC2.5V; Reverse working value: m30-R7N: Release time: when 18V is not less than 0.35S, when 24V is not less than 0.5S, the rear loop current is reduced from 5A to 1.5A, 0.3S when the power is cut off Contact resistance: not more than 0.10Q.

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 relay contacts are connected to DC24V1A resistive load; its electrical life is 2×106 times.
