RB5100  is a complete solution for controlling the railroad crossing on the Model Railroad.

Features:

· 3 PWM outputs. O1 and O2 by default are configured to perform periodical blinking as railroad crossing light does.

· 1 output for the speaker. When decoder activates the railroad crossing it will play the alarm sound.

· 1 track occupancy sensor which allows activating decoder on a specific railroad track when it is occupied by the train.

· 2 servomotor outputs which are working parallelly.

· 1 manual input. The external button could be connected to it for the manual control of the railroad crossing decoder.

· 3 potentiometers. Allows configuring of the upper and lower position on the servomotor as well as speeding of barrier’s opening or closing.

· DCC input. Allows configuring of the internal CV values and controlling a decoder from the command station.

· Power input. Allows decreasing of a current supply via DCC input from the command station. (Useful for the bigger scale Model Railroad). Should be connected to DCC inputs if the external power is not used.
