Circuit controller in block system for a.c. model railway records when wheel set in block region, outputs one or more electrically separate mass pulses when last wheel set leaves block region

摘要

The device records when a wheel set is in the block region and outputs one or more electrically separate mass pulses when the last wheels et leaves the block region. The time between the last wheel set leaving the block and triggering the mass pulse and the pulse length are adjustable. The recording of a wheel set in the block is visually indicated with a LED and the circuit controller has two or more electrically separate switch outputs.
