IR Train Detector with on-board c/o relay BlockSignals - BOD2-RLY


Detects trains and operates a built-in relay.


Quick and easy way to detect trains anywhere on your layout, even in tunnels


Detects passing trains using its in-built infra-red sensor


Very easy to connect to simple indications on a control panel or to add as inputs to computer systems


Operates from 8V to 25V DC


Low current output (+5V DC) to feed LEDs, signals or small relays


No soldering required, all components are ready wired


No programming necessary (but you can adjust all settings if you wish)


We often are asked how to detect trains in tunnels, or on layouts where enthusiasts run their trains in twilight, or even in complete darkness.  In these situations, photocell operated detectors will not work, and so you need a detector with a built-in light source.


The BOD2-RLY has a built-in infra-red detector which can "see" in the dark and can detect trains in these situations.


The module has a small relay built-in. When a train crosses the sensor, the relay coil is energised, and the relay common contact (labelled COM) moves from the normally-closed (NC) position to the normally open position NO.


After the train clears the sensor, the module de-energises the relay and the relay contact moves to the normally closed position.


A delay can be set before this occurs to allow a train indication to remain present for a period, or the indication can immediately reset.  The module can also be set to ignore the gaps between carriages. With a delay, the module can operate a two aspect signal, switching to red when a train crosses the sensor, and back to green a pre-set time after the sensor is cleared.


There are several programming options available (see later).


You can power the module from 8V-25V DC.  The module reduces the supply voltage down to 5V to feed attached leds, etc.
