DZ-1050 3-Color Trackside Signal | O-gauge
- Exclusive optical sensors in the base of each signal detect an adjacent train.
- Just set them down and connect 2 wires to power for a working signal.
- When the train passes the signal, the indication will change to RED or stop and hold until the train has passed. 4 seconds after the train passes, the signal will change to YELLOW or caution.
- After 4 more seconds, it will change back to GREEN or clear.
- The signal only needs (9-18V AC or DC) power to operate, but it does have an input (YELLOW) and an output (WHITE) for additional possibilities.
- The "V" version signals have variable delay (1-60 sec.) which can be set by the user.
