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 photocell detection (requires adequate overhead lighting). 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 photocell (included) the signal turns red (or stop position). When the train clears the photocell 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 photocell (individual sensitivity adjustable). Additional photocells available.
• Current limiting resistors included
• Powered from AC or DC (draws about 25mA)
• Solid State Design (1 year limited warranty)
