TFL Traffic Light Controller (TFL-1, TFL-2 & TFL-4) 12V DC

About the Product

The BLOCKsignalling TFL Traffic Light Controller is a versatile traffic light sequencing module designed for model layouts, playground displays, roadworks simulations, and other miniature traffic control applications. The module can operate in one, two, or four channel versions, the controller automatically operates standard red, amber, and green traffic light heads with fully adjustable timing settings.

The module uses relay-controlled outputs to drive traffic light heads and allows independent adjustment of red, red and amber, green, and amber phases. Multiple operating modes are available, allowing traffic lights to operate sequentially or in paired opposing directions depending on the installation requirements.

A built-in skip button allows the current phase to be instantly advanced, making setup and testing quick and straightforward. LED indicators on the PCB provide visual confirmation of power, processor operation, and traffic light status.

Key Features

• Automatically operates standard red, amber, and green traffic light heads.
• Available in single, dual, or four-head traffic light controller versions.
• Adjustable timing for red, red and amber, green, and amber phases.
• Optional red and amber phase can be disabled for country-specific operation.
• Supports sequential junction control where only one traffic route shows green at a time.
• Alternative paired operation mode for opposing traffic flows.
• Built-in skip button for rapid testing and setup.
