When reliability isn't optional, you specify RIB®.
For over 55 years, Functional Devices has been the name automation contractors, HVAC engineers, and building system integrators trust. Their RIB® (Relay in a Box®) line is the most recognized enclosed relay in North America — and for good reason.
✅ Field failure rate below 1 in 16,000 units
✅ Industry-leading 10-year warranty
✅ 100% factory tested before it ships
✅ Made in Indiana, USA since 1969
Whether you're specifying relays for a DDC system, sourcing current sensors for energy management, or building out a lighting control panel — the full Functional Devices line is now available through INDECO.
We stock the complete RIB® series: enclosed industrial relays, split-core current sensors, Class 2 power supplies, and more, ready to ship.
