    • Connect lines representing up to four sets of points for general interlocking
    • Will power a colour light signal from 5v; alternatively, use the 5v line out as the input for a servo driver (not supplied) for a semaphore signal
    • Connect a momentary contact lever to the input, which will only operate the signal if the interlocking conditions are met.
    • Requires 1x 5v power supply
