Functional Devices was founded in 1969 by Albert Rittmann, an engineer with a love for tinkering with electronics. Over the years, they have expanded their product lines to serve a broad range of industries including building automation, HVAC, lighting, electrical, panel shops, fire & safety, wireless, and power monitoring. Functional Devices are best known for their RIB® (Relay in a Box®) brand product lines. They manufacture their products in the heartland of Indiana where every unit is tested before it leaves the production floor to ensure our customers get the product quality they have come to expect. RIB’s ease of installation, product performance and durability are why our customers enjoy confidence and peace of mind in every box with each RIB purchase.
