Model: MS2909
MS2900Chassis-Mount Pulse Shaper (Pulse Isolator) with Isolated Dual Output

DESCRIPTION
The MS2909 is a pulse shaper (pulse isolator) that converts
pulse train signals into mutually isolated dual channel pulse
train signals.
▽ A multi-slot chassis provides ease of maintenance andhigh-density mounting.
▽ Input, output 1, output 2, and power circuits are allisolated from each other.
▽ Equipped with a fuse on the DC power line asstandard.
