ASP1-NS Automatic Signal Control

About the Product

The Automatic LED Signal Controller ASP1-NS is a compact module designed to automatically operate multi-aspect LED signals whenever a train passes over its built-in infra-red sensor. It provides effortless, realistic signal control on model railways, fading LEDs to simulate incandescent bulbs and requiring no soldering, programming, or complex wiring.

It offers a simple and reliable way to add automation to 2-, 3-, or 4-aspect signals, making advanced signalling accessible to all modelers.

Key Features

• Controlling multi-aspect LED signals on model railways has never been easier.
• Detects trains passing overhead using its in-built infra-red sensor.
• Fades signal LEDs in and out to simulate incandescent bulbs.
• Very simple to connect to signals.
• No soldering required — all components are pre-wired.
• No programming required, but all settings are fully adjustable.
• For use with common-cathode LED signals (not bulb-based signals).
• Requires a 12V DC power supply.

Electrical Specifications

• Operates from a 12V DC plug-top power supply.
• Current draw is less than 0.01A, allowing many modules to run from a 0.5–1A supply.
  
• Built-in resistors mean no external resistors are required.
  
• Incorrect polarity causes no damage, though the module will not operate.
  
• Not suitable for use with unregulated accessory outputs on train controllers.
