Ramsey Electronics Model No. ICI1

Do you have a ton of old remote controls around, or even a
universal remote? Put those to real use by training this unique
kit to recognize the remotes, and allow you to turn a set of four
relays on and off! Turn on lights, TVs that have no remote,
small appliances and more!

•

IR Receiver module with sensitive element can receive your
remote control up to 11 meters away.

•

Control up to four devices independently via relays.

•

E-Z screw terminals hookup for each output.

•

Easy to train to recognize almost any remote control!

•

Universal 7-15V AC or DC operation. Use our AC-1 wall adapter for
battery free operation.

•

Convenient LED indicator lets you know Infra Red status.
