Mining explosion-proof and intrinsic safety type sound and light combination signal device

KXH127 (36) Mining Explosion proof and Intrinsic Safety Sound and Light Combination Signal Device. (hereinafter referred to as the signaler)

It is a mining explosion-proof and intrinsic safety type, suitable for signal communication in belt transportation and winch transportation in underground explosive gas environments. Convenient production, labor-saving, increased safety and reliability of underground operations, and improved economic benefits. Has broad promotion prospects and practical value. This device can replace the original combination of electric bell signals and sound and light signals from other domestic manufacturers.

Performance Characteristics

a、 Sending signal: Press the explosion-proof signal button on this unit to send sound and light signals (dots) to all connected units on this unit.

b、 Receiving signal: Each connected unit can receive the sound and light signals emitted by any unit, and emit>85dB audio signals through speakers and visible light signals within 20 meters through light-emitting diodes.

c、 Single power intercom: This device connects various units through power lines to achieve power carrier intercom function without changing the wiring method of the existing coal mine explosion-proof signal device power box.

d、 Emergency stop function: When the emergency stop button is not pressed, the K1 and K2 terminals are normally closed, and the control light in the middle does not light up. When the emergency stop button is pressed, the K1 and K2 terminals become normally open and self lock, and the control light in the middle lights up to unlock. You must press the emergency stop button again. In this way, the red light in the middle will not light up, and K1 and K2 will become normally closed. The control power supply for K1 and K2 will be determined according to the site.
