Product Description
Easy to Install on DC layouts - only 2 wires - One to each rail
Brand new DC-powered signals from Pro Tech have just now hit the market. Be the first in your club to show off these easy-to-install LED signals. This one is a single green light that turns on if it's safe to proceed and turns off when it's not. It only has two wires - one to each rail - and changes automatically when the polarity of the track changes. For example, if you hook it up to the block of track that your locomotive is approaching, if that block is either unpowered or if the polarity is incorrect, the signal will be off and you should not proceed. If the block is powered and the polarity is correct, the light will be green and you may proceed. They also work well with opto or IR sensors that detect the presence of a train on the block ahead. They are pre-wired with resistors so installation is simple. They operate with DC power only. DO NOT use for DCC or AC powered layouts.

This signal contains a green LED that has a current limiting resistor already installed. You can hook up directly to transformer's (DC) track current or any DC supply of 2-16 volts. Not to be operated on AC current. |
