DC 12V Intrinsically Safe Emergency Stop Switch

one.Overview
KHJ0.5/24 (B) mine safety sort clever abrupt cease change (hereinafter referred to as the abrupt cease change) is ideal for the coal mine with explosive gas (CH4) environment and open-pit coal mine, coal preparation plant, this kind of as the workplace, as for mine belt conveyor safety of electrical handle gadget of the unexpected emergency stop sign detection and managing deviation, longitudinal tear defense box and capabilities in the junction box.

two.Electrical function
2.one.Self-locking function: When the two sides of the sensor are stretched in area, the sensor realizes self-locking. At this time, the external power is eliminated and the fault sign output is managed.
2.2.Station alignment: When the sensor operates, it outputs the fault signal and station number details at the identical time, helping the operator to speedily lock the fault spot.
2.3.JCPT sign prompt: When the sensor is working, the large-brightness crimson lights on the two sides of the sensor light up, indicating the sensor position.
two.four.Digital registration screen of 64 unexpected emergency stop fault points.

3.Electrical parameters
3.one.Rated voltage: DC12V
3.2.Intrinsically protected working present ≤40mA
3.3.Get in touch with potential: DC24V / .5A
three.four.Right after the pad make contact with resistance ≤0.1Ω, vibration, shock ≤0.2Ω
three.five.Explosion-evidence mark: Exib I .

four.Operating surroundings
four.one.Ambient temperature: -five ºC ~ + 40 ºC
4.two.Typical relative humidity: not more than ninety eight% (+ 25°C)
four.three.Atmospheric strain: 80kPa ~ 106kPa
four.four.No substantial vibration and shock
four.5.Underneath the coal mine, there are explosive and hazardous environments such as fuel and coal dust, but there are no occasions that hurt the insulating corrosive gasoline.
