BOD4-RLY Infra-Red Train Detector & Relay for Faller 161675

The BLOCKsignalling BOD4-RLY is a compact infra-red train detector with a built-in relay, designed to detect trains or vehicles and trigger actions on your layout. It provides a simple and reliable way to automate signals, accessories, and animations, even in hidden areas such as tunnels. When a train passes over the infra-red sensor, the module detects it and activates the relay. Once the train clears the sensor, the relay resets, with optional delay and timing features for more realistic operation. A range of built-in programs and adjustable settings allow the behavior to be tailored to suit different layouts and applications. Key Features Detects trains and vehicles using an included infra-red sensor. Built-in relay rated up to 1.5A at 24V DC for controlling accessories. Quick and easy installation, including use in tunnels and hidden track sections. Multiple built-in operating modes for different applications. Adjustable delay before relay activation and reset. Optional randomised timing for more realistic behaviour. Ability to trigger only a proportion of detections for varied operation. Built-in +5V output for driving LEDs, signals, or small relays. Adjustable sensor sensitivity to suit different layouts. No programming required for basic operation, with advanced configuration available if needed.
