Model SAD-SBCA Signal Animator by Logic Rail Technologies. Detects trains and controls Tomar semaphore motors, 2 & 3-light bulb-based signals and PRR/B&O position light signals (both bulb-based and LED signals wired with a common anode [positive]). Creates near-prototypical block signal behavior without spending lots of money. Uses infrared (IR) detection (works in light or darkness). Works with both DC and DCC layouts. Complete instructions included. Easy to install.

Requires no modification to track wiring or rolling stock.

When the train covers the IR sensor the signal turns red (or stop position). When the train clears the IR sensor the signal turns yellow (or caution position) after a delay (10 or 30 seconds, selectable). After another delay the signal turns green (proceed position). Complete instructions included - easy to install.

Features:

• Controls Tomar semaphore motors, searchlight and 2 & 3-light bulb-based signals, and LED-based position light signals wired with a common anode (positive) (sold separately).
• Adjustable yellow hue for searchlight signals
• Includes 1 IR sensor component set (individual sensitivity adjustable). Additional IR sensor component sets available.
• Current limiting resistors included
• Powered from 7-9V AC or 9-12V DC (such as the WT1A together with the 12VPSR - not included), and draws about 100mA
• Solid State Design (1 year limited warranty)
