OD-1-IR Optical Detector. The model OD-1-IR optical detector utilizes an infrared sensor (included) mounted between the rails for detection. Works with both DC and DCC Layouts.

The OD-1-IR has one red output and one green output for driving LEDs in a variety of wiring schemes (2-lead bipolar LED, 3-lead bipolar LED, individual red and green LEDs) and a separate red output for driving higher power devices such as lamps, relays, sound modules or other external circuits.

Requires no modification to track wiring or rolling stock

Whenever the photocell is covered the OD-1 will activate its red outputs. When the photocell is uncovered the OD-1 will activate its green output.

Features:

• 2 or 4 second detector release time (selectable)
• Includes a bipolar (red/green) LED and appropriate current-limiting resistors
• The LED outputs are rated at 25mA; the higher power output is rated at 150mA
•  
• Powered from 7-9V AC or 9-12V DC (such as the WT1A together with the 12VPSR (not included), and draws about 100mA with the included LED
• Solid State Design (1 year limited warranty)

Use this version if you have low light/no light (night time) scenarios. For consistent overhead lighting see the OD-1 photocell detection version.
