Product Introduction:

KTA162 Intrinsically Safe Ground Mounted Telephone Coupler


KTA162 Ground Output Intrinsically Safe Telephone Coupler, also known as an underground telephone safety barrier, is a dedicated device for connecting program-controlled switches or dispatch communication systems with intrinsically safe telephones. It serves as an intermediate isolation device between the control area's program-controlled switch and the hazardous area's intrinsically safe explosion-proof telephone to ensure safe communication. Its function is to isolate interference signals, prevent overvoltage and overcurrent in telephone lines, thus ensuring the safety of underground communication networks and work environments. It accomplishes the task of production dispatching and communication between safe areas and hazardous areas.

Converged Communication: A Communication Method in the Digital Era


Features


■   Scope of Application

      The associated equipment connecting the program-controlled switch or dispatch communication system with the intrinsically safe telephone is an intermediate isolation device for safe communication between the program-controlled switch and the intrinsically safe explosion-proof telephone in special industries such as coal mines, non coal mines, chemicals, and power.


■   Function and Function

      To isolate interference signals, prevent overvoltage and overcurrent in telephone lines, and ensure the safety of underground communication networks and workplaces.


■   Configuration capability

      A single standard rack mounted 1U structure, with a capacity of 32 doors, can be combined and stacked in any way, and can be used as a user coupler for hundreds or thousands of lines.


■   Equipment structure

      The shell is made of iron shell material, and the chassis has a novel and beautiful appearance, full of modern sense. The structure is reasonable and firm, small in size, light in weight, easy to use, and has good call quality.
