Repeater-Line Pulse Extender (Instant)

2×N×2
flat, silent

circuit delay: 0 ticks
output pulse: input pulse length (=IPL) + up to IPL ticks (max 4) per repeater

Repeater-Line Pulse Extender (Delayed)

2×N×2
flat, silent

circuit delay: 4 ticks
output pulse: IPL + up to 4 ticks per repeater (excluding first)

Rising Edge Dropper-Latch Pulse Generator

2×6×2 (24 block volume)
flat, silent

circuit delay: 5 ticks
output pulse: 5 ticks to 256 seconds (regardless of IPL as long as its shorter)

The dropper contains a single item. The middle hopper contains one or more items depending on the desired pulse duration.

Rising Edge Hopper-Clock Pulse Generator (Flat)

2×6×2 (24 block volume)
flat

circuit delay: 1 tick
output pulse: 4 ticks to 256 seconds (regardless of IPL as long as its shorter)

Rising Edge Hopper-Clock Pulse Generator (1-Wide)

1×6×3 (18 block volume)
1-wide

circuit delay: 1 tick
output pulse: 4 ticks to 256 seconds (regardless of IPL as long as its shorter)

RS NOR Latch Pulse Extender

3×3x(4+N)
silent

circuit delay: 2 ticks
output pulse: input pulse length + 8 ticks per repeater

Opposed-Piston SR Latch Pulse Extender

3×N×2
flat

circuit delay: 1 tick (1.5 tick if the output powers a piston)
output pulse: 8 ticks per repeater (regardless of IPL as long as its shorter)

Breaks itself and requires manual reset if the IPL is greater than the configured OPL (output pulse length)!

Fader Pulse Extender

2×N×2
flat, silent

circuit delay: 0 ticks
