In the face of complex and variable mining conditions, real-time monitoring and multi-parameter control of equipment are of critical importance. Developed by Yichang Zhaofeng Instruments, the KXB24/127 Mining Explosion-Proof Display Controller meets the stringent requirements of underground coal mines and other high-risk operations. The device integrates multi-signal input/output capabilities, a clear and intuitive display interface, and reliable explosion-proof performance. It is designed for applications where the number of monitored and controlled parameters is limited and control modes are relatively fixed. It can directly replace small PLC systems, simplifying control system development and significantly reducing user operation and maintenance costs while enhancing system reliability.

KXB24/127 Mining Explosion-Proof Display Controller

1. Powerful Integrated Measurement and Control Capabilities

The KXB24/127 Mining Explosion-Proof Display Controller offers strong multi-parameter monitoring and control functions. It can accurately measure key variables of mining equipment such as pressure, temperature, liquid level, flow, and rotational speed, providing comprehensive data support for stable operation. Whether in coal mining faces, tunneling roadways, or fan chambers, the controller delivers excellent detection capability, enabling real-time monitoring of equipment operating conditions.

The device provides six cable entries, supporting four 4–20 mA analog inputs, one frequency pulse input, and one optional output of either a CAN bus signal or RS485 bus signal. It also offers one 4–20 mA analog output and three passive relay switch outputs. This combination of input and output signals ensures the flexibility to meet diverse monitoring needs in harsh mining environments.

2. Clear and Intuitive Display

To enable operators to quickly and accurately obtain equipment information, the KXB24/127 is equipped with a high-brightness 3.3-inch OLED display with a resolution of 240×128. It clearly presents data from up to five input channels. In addition, the screen can promptly display alarm information such as high/low temperature warnings and sensor module faults. When an abnormal condition occurs, operators can immediately detect the issue and take corrective action, effectively preventing accidents.

As an example, when displaying four temperature signals and one pressure signal, the device processes five 4–20 mA inputs, shown in display cells A, B, C, D, and E. For each input, users can set the measurement range, unit, and decimal point. The bottom-right corner of the display indicates the states of the three passive relay switches, where “ N” means the relay is closed and “Y” means the relay is open.

3. Reliable Explosion-Proof Performance and Strict Compliance with Standards

Explosion-proof performance is a critical indicator of mining equipment reliability. The KXB24/127 adopts a stainless steel explosion-proof enclosure and is designed and manufactured in strict accordance with GB/T3836 and related standards. Its explosion-proof certification is marked as ExdbⅠMb, and its safety has been rigorously tested and certified by authoritative organizations, effectively preventing internal and external explosion hazards and ensuring safe mining operations. The explosion-proof certificate number and safety mark are clearly indicated on the nameplate, giving users added confidence. The product series complies with Q/YZY190 “KXB24/127 Mining explosion-proof Display Controller.” From design and production to testing, every stage is strictly controlled to guarantee reliable product quality.

4. Easy Installation, Convenient Settings, and Wide Applications

The product features a compact structure for easy installation and adapts well to harsh environments. It uses explosion-proof magnetic keys that are fully isolated from external circuits. Whether in the damp and dusty conditions underground or in complex environments on the ground, it operates reliably. It can be paired with field transmitters and supports RS485 Modbus RTU protocol, CAN standard frame, or CAN extended frame for reliable data transmission.

Thanks to these functions, the KXB24/127 can be widely applied in temperature monitoring and control of underground and surface mining equipment. It enables the construction of small-scale control systems, greatly simplifies system configuration, and enhances the level of automation and monitoring of mining equipment, helping enterprises improve production efficiency and reduce operating costs.

The KXB24/127 Mining Explosion-Proof Display Controller delivers stable performance and comprehensive functions, making it suitable for a wide range of mining monitoring and control scenarios. It effectively enhances both automation and safety. For further product details or technical support, please feel free to contact Zhaofeng Instruments.
