Model: MS2904
MS2900Chassis-Mount High-Level Signal Conditioner (Isolator) with Isolated
Dual Output

DESCRIPTION
The MS2904 is a chassis-mount high-level signal conditioner(isolator) that converts high-level DC input signals into
mutually isolated dual channel DC output 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.
