nWa - Maintained single shot trailing edge
When the supply voltage U is supplied, the output relay R remains in off-position (green LED U illuminated). As soon as the supply voltage is interrupted, the output relay switches into on-position and the set interval T begins (green LED not illuminated). After the set interval T has lapsed, the output relay switches into off-position. When the supply voltage is reconnected before the interval T has lapsed, the unit continues to perform the actual single shot.
U - supply voltage; R - output state of the relay; T - measured time; t - time axis
