The CXH18 intrinsically safe programmable display operation box is suitable for mines with gas and coal dust explosion hazards.
Product Overview
The CXH18 mining intrinsic safety programmable display operation box adopts an intrinsic safety design and is suitable for underground mines with gas and coal dust explosion hazards. The control box can achieve on-site control, data acquisition, transmission, and alarm functions. The operation box is equipped with a 10.1-inch color intrinsic safety touch screen, which displays clearly and is easy to operate; Each operation box has an independent power supply to ensure safe maintenance; Equipped with an Ethernet data upload interface, it can achieve data transmission with other substations and main stations. The internal controller integrates a dual controller mode of PLC controller and Mine Hong controller for users to choose from.
Safe and reliable
Mining intrinsic safety design, explosion-proof display screen, suitable for harsh coal mine underground environments that are flammable and explosive; Each operation box has an independent power supply to ensure safety during maintenance.
Powerful
The control box can achieve on-site control, data acquisition, transmission, and alarm functions. It has various operation buttons such as knobs, buttons, multi gear selection switches, and emergency stop operation switches.
Multi channel input/output
Equipped with 8 passive contact signal inputs/outputs; Equipped with 12 channels of 4mA to 20mA current type analog signal inputs; It has 9 PT100 analog signal inputs.
Working Principle
Intrinsic safety power supply
The KXJ-660 control box outputs an inherently safe power supply, providing stable power to the CXH18 operation box. Through circuit energy limiting design, it ensures safe operation in flammable and explosive environments.
Button signal acquisition and transmission
-
The output signal of the operation box button is processed by an intrinsic safety circuit and transmitted to the programmable control box through an Ethernet interface, achieving real-time and reliable transmission of control instructions.
Real time display of data
After processing signals, the programmable control box feeds back on-site data (such as equipment status and parameters) to the operation box display screen through Ethernet, achieving real-time visual monitoring and operation feedback.
