KXH127 mine flameproof and intrinsic sound and light signal device with emergency stop type voice sound and light alarm Item NO.: 335138

1. An overview of the
This product is a comprehensive mine explosion-proof and intrinsically safe acousto-optic signal device, which integrates voice call, electric bell and emergency stop blocking.
Use 8.8 inner hexagon screw fastening, product technical requirements are more strict.
The model of the acousto-optic annunciator is KXH127. The explosion-proof type of the annunciator is mine explosion-proof and safety type. Explosion mark :EXDIMB.
Model description of mine explosion-proof and intrinsically safe acoustooptic annunciator:
KXH: mine signal equipment
127: rated working voltage is 127V
Suitable for coal mine underground methane, coal dust explosive mixture, but no damage to the corrosive gas insulation occasion.

2. Product structure features
Acousto-optic signal set acousto-optic, signal, call, emergency stop function as one.
The structure is designed to directly introduce the flameproof structure, and the flameproof wiring terminal is installed in an independent wiring cavity. There are four wiring outlets in the wiring cavity, and two wiring outlets are used for signal power supply input and output.
The circuit diagram is optimized. The power supply adopts linear circuit with better safety performance, double overcurrent voltage protection, and relay isolation for higher safety.
