CTC-DC01 Ground Output Intrinsically Safe Telephone Coupler

Overview
- Also known as "intrinsically safe telephone barrier," it safely isolates the programmable switchboard or dispatching system from the intrinsically safe telephone.
- Prevents overvoltage/overcurrent in telephone lines, ensuring communication safety in underground or hazardous environments.
Key Features
- Safety Isolation: Prevents overvoltage and overcurrent in telephone lines, protecting the intrinsic safety system underground.
- Standard 1U Rackmount: Capacity up to 32 lines, expandable to hundreds via stacking.
- Iron Shell with Plastic Coating: Durable, lightweight, and easy to install.
- Applications: Suitable for coal mines, non-coal mines, chemical plants, power facilities, and other scenarios requiring intrinsic safety protection for lines.
Core Parameters
- Single Unit Capacity: 32 ports, freely combinable and stackable
- Interface Type: Intrinsically safe telephone line / PBX trunk port
- Power Input: AC220V ±10%
- Dimensions: 19" 1U (approx. 44.5 mm in height)
Typical Applications
- Perform safety isolation between mining intrinsically safe telephones and surface switches
- Protective coupling between high-risk extreme zones and ordinary telephone lines
