LU-MOD quad latching signal interlock

Circuit card for operating signalling on modular model railways depicting the London Underground built to the LU-MOD standard.

    • Connect up to four outputs that require protection for setting reverse but not setting normal (e.g. signals)
    • Use the built-in outputs for colour light signals; alternatively, connect the outputs to a suitable driver module (not included) to operate servo controlled semaphore signals
    • Connect up to four momentary contact levers or push-buttons to control the outputs – the output will only be triggered if the conditions should be met.
    • Connect up to 3 inputs for each output, each of which must be active (at 5v) before the output is activated.
    • Connect up to a further 3 inputs for each output, none of which may be active (at 5v) before the output is activated.
    • Unused inputs can be bypassed by connecting them directly to the 5v power supply (enabling inputs) or not connecting them (disabling inputs).
    • Requires 1x 5v 1A power supply
    • Size: 100mm x 100mm
