Block Signalling SEC1B-DC Section Control Module The BLOCKsignalling Section Control Module is designed for DC layouts, to protect a section of track to prevent more than one train entering that section at one time. Monitors trains entering and leaving a section of track Automatically sets the signal at the start of the section to danger (red)Isolates a section of track to stop trains at the signal Communicates to previous sections to ensure they show yellow (and double yellow) aspects when 3- and 4-aspect signals are used Last section can simulate returning back to clear using timers to provide realistic operation when 3- and 4-aspect signals are used Points which are not set in the trains favour can force the signal to danger Signal can be forced to danger by an external input (useful for starter signals) Suitable for 2-, 3-, and 4-aspect led signals (SEC1A-DC for common-cathode and SEC1B-DC for common-anode) Bidirectional running with 2-aspect signalling at each end of the line New: Additional Station Stop Modes New: Additional Dapol output Remembers whether the section is occupied after the power is removed and automatically restores the signals after power returns Simple to setup, but also fully configurable to provide the most realistic operation Requires a 12V DC Power Supply
