To test the block boxes during development a replacement for a station is needed. It should reflect the station with the functions relevant for the block without being unneccesary complex. The circuit is designed for a 12 V supply, but may be easily modified for use with 5 V or 24 V. |
See the circuit diagram. All switches and relays are drawn in default position, i.e. signals at stop and relays not energized. The circuit consists of the following components:
