Why Contractors Prefer RIB® Relays

Faster Installs, Fewer Callbacks: Why Contractors Prefer RIB® Relays

As an electrical contractor, have you ever spent time:

• running wires in tight ceilings?
• chasing down voltage issues?
• doing rework?

These “little stuff” tasks can slow you down. They burn time, eat labor, and drag budgets into the mud.

We have the solution: RIB® relays from Functional Devices.

RIB® Relays Eliminate Delays

Electrical relays can cause delays because of a wire that takes too long to install, a mislabeled terminal, or a component that doesn’t match specs.

That’s exactly why so many contractors rely on Functional Devices’ RIB® (Relay-in-a-Box®) relays. They come enclosed, prewired, and ready to install. 

• No fuss. 
• No on-the-fly fabrication. 
• No “why isn’t this working?” when you’re trying to wrap up the job.

How RIB® Relays Help on the Jobsite

Building a standard relay usually means gathering a box, checking coil voltage, creating wiring terminals, labeling everything, and hoping someone on the crew doesn’t mix up the connections. It’s not hard, but it’s time-consuming—especially if you don’t get it right the first time and need to go back to fix it. 

Functional Devices’ RIB® relays skip all the prep work and eliminate rework. Our enclosures are built in. The wires are already landed. The labeling is clean. You open the box, and it’s pretty much “mount-and-hook.” 

RIB® relays remove the guesswork and grunt work of relay installs, while helping you:

Reduce Site Delays 

Every contractor knows what kills a project timeline: delays, scope changes, and the classic: “it’s supposed to be here, but it’s not.” When things go sideways, components that don’t require a lot of extra work help claw back time. Functional Devices’ RIB® relays keep things moving, by:

• Being installation-ready
• Making coil voltage easy to identify
• Minimizing wiring with prewired leads
• Making control wiring easy 

Lower Labor Costs

Contractors want to simplify installation and avoid callbacks. RIB® relays reduce wiring time and make installation easy, thereby minimizing labor needs and lowering labor costs. 

Reduce Prewired Leads 

RIB® relays take care of terminal wiring at the factory. That means fewer crossed wires, fewer mix-ups, and fewer slowdowns.

Simplify Mounting 

Every RIB® relay arrives in a durable enclosure with screw holes and knockouts. There’s no digging around for the right box or bending metal to make something fit where it clearly doesn’t want to fit.

Out-of-the-Box Functionality

Even new crew members can install RIB® relays cleanly and confidently. Our consistency helps keep labor schedules tight and predictable. Shaving even five minutes off of a relay install might not sound like much—until you multiply it across dozens (or hundreds) of relays.

Built for Reliability in HVAC, Lighting, and Automation

Callbacks can derail a whole week. That’s why reliability matters, and why we build our relays to hold up in the field.

Many RIB® relays are UL-listed and built to take the abuse of rooftop units, mechanical rooms, electrical noise, vibration, temperature swings. Whether you’re tying into HVAC, lighting, or building automation systems, our relays are made to stay off your callback list.

Versatile RIB® Options for Every Electrical Application

Contractors appreciate the many different RIB® relays we offer. Whatever the job, there’s an RIB® relay. Our lineup includes:

• Power relays
• Pilot relays
• Current-sensing relays
• Wireless lighting control relays
• Low-voltage and line-voltage models

Standardizing on one family of relays makes your electrical crews faster. Less guessing, less searching, less troubleshooting.

Consistency is king on the jobsite.

Fewer Mistakes, Fewer Callbacks 

Most callbacks come from simple mistakes—miswiring, unclear labeling, installing the wrong relay for the voltage, or rushing under pressure. We built RIB® relays to eliminate those pitfalls.

Clear Labeling and Easy Identification

You can confirm coil voltage, relay function, and wiring at a glance.

Simplified Troubleshooting

If something downstream acts up, checking the relay is quick and simple. The prewired design makes verification easy.

Factory-Assembled Consistency

Because we assemble our RIB® the same way every time, you’re not relying on field wiring done while someone’s balancing on a ladder.

Supported by U.S.-Based Customer Service and Industry Expertise
