Visit my online shop at https: //mXion.de/ For better prices! => When using AC motors, use our MDC! You can purchase an mXion SMB here purchase (suitable for all tracks, all voltages). You can find more information in the Operating instructions => https://www.micron-dynamics.de/sitecake-content/mXion%20SMB.pdf The mXion SMB is ideal for railway crossings with powered barriers (e.g. Pola-G, Faller, etc...). The module not only controls the barriers but also provides alternating flashing to match the barrier movement. 2 contact inputs for control can be controlled via switches, buttons, reeds, light barriers or directly via a separation point in the track. The operating voltage doesn't matter. Speed and travel time can be adjusted using potentiometers. - 2 potentiometers for speed and tra.
