Features and Benefits

The MSU140 offers a number of improvements over other
IR Extender Main System Units:

• Universal system—compatible with virtually all brands

of A/V equipment and remote controls.

• Accommodates one IR sensor or keypad.

• Provides four flasher outputs via convenient 3.5mm

jacks.

• System feedback LED confirms operation.

• 3-30V AC/DC status input. Provides system status to con-

nected sensors and keypads.

• Expandable—an IRH610 IR expansion hub can be used

to provide additional inputs.

• Printed circuit board design assures high reliability.

• Low profile and small footprint with integrated mount-

ing wings that allow for both horizontal and vertical
installation.

• UL listed regulated in-line power supply with universal

voltage capability.

• Two year parts and labor warranty.
