Types of Unit

We supply the following Infrared Units:

IRDOT-1

The IRDOT-1 is the basic train detection unit. This lights a (control panel) LED. It has an electronic "train detected" switch to activate our other units, a second green "not detected" LED, or a relay. It is also possible to operate a bicolour LED to give for example green "not occupied", red "occupied". The switch may also operate a relayor opto-isolator for interfacing to a computer etc. More Information ...

IRDOT-1D:

Outputs are identical to the IRDOT-1. It detects the train immediately but takes 4 seconds to undetect, this is to provide continuous detection of the train. As a train crosses the IRDOT-1 the LED will flicker off at each gap between wagons or coaches , the IRDOT-1D's LED will remain lit during these gaps due to the 4 second delay. More Information ...

IRDOT-2

:

This operates an LED and a built-in changeover relay, allowing it to replace reed switches . The relay contacts provide electrical isolation to enable interfacing to computers, programmable logic controllers, etc. As well as detecting trains they have been used as proximity detectors for movement of model crane arms etc. More Information ...

IRDOT-2D:

This has the same outputs as the IRDOT-2, but also has a 4 second undetect delay to prevent the LED flickering and the relayrepeatedly switching as the train travels over it.More Information ...

IRDOT-3

This has a built in double pole relay and the facility to also operate both detect and undetect LED's or a bicolour LED.. The size and voltage specifications are the same as the IRDOT-3D.More Information ...

IRDOT-3D

As the above with the addition of the following selectable delays: 3, 6, 9, 12, 15, 18, 21, and 24 seconds. These are selectable by connection to the terminal block.More Information ...

IRDOT-P:

This operates solenoid (PECO SEEP etc) point motors on detecting a train. It also has a train detected LED. These units can be used to operate automatic reverse loops and storage sidings.More Information ...
