Every field tech has a set of go-to parts—those versatile components that save time, eliminate headaches, and keep systems running without endless troubleshooting. In the world of building automation and control wiring, Functional Devices’ RIB® products have become core pieces of that toolkit. These compact, pre-wired devices offer robust performance, flexible application options, and dependable reliability on countless jobs.
Beyond the familiar favorites like universal relays, there’s a wider set of RIB products worth keeping in your truck or on the shelf. The right mix of relays, logic devices, and current-sensing products can turn a tricky control problem into a quick fix and reduce the need for extra panels or custom wiring.
Below is a refreshed look at some must-have RIB® offerings every technician or engineer should know in 2026.
Expand Control Options with Multi-Output Logic Relays
RIBMN24Q Series (Q2C, Q3C, Q4C)
When your controller runs out of discrete outputs but still needs to switch multiple devices, the RIBMN24Q Series steps in. Feed a single analog signal (0–5/10 Vdc), and these units generate multiple binary outputs—without forcing you to add larger panels or multiple separate relays.
Each model supports a different number of outputs, giving you options that scale with the job.
Combine Sensing and Switching in One Box
RIBHX24BA
Want control and verification in a single device? The RIBHX24BA hybrid relay and current switch combines both functions so you can enable a load (like an exhaust fan) and simultaneously receive confirmation that it’s running, all from one fixture. It saves space and declutters wiring runs.
Improve Monitoring with BACnet-Enabled Devices
RIBMNWLB-7-BC
Large air handlers often have multiple safety devices that need monitoring. Instead of pulling dozens of discrete wires back to a controller, the RIBMNWLB-7-BC is a BACnet-ready safety cut-out device that lets you capture up to six hardwired input devices plus a seventh fan status signal—all viewable over BACnet. Its compact footprint and communication convenience make it ideal for modern air-handling control schemes.
RIBMNWD12-BCDI
Need to bring many binary inputs back to a BAS panel without heavy cabling? The RIBMNWD12-BCDI accepts up to 12 binary inputs and broadcasts them via BACnet, saving wiring costs and simplifying system integration, especially in retrofit environments.
RIBMNW24B-BCAI
Designed for decentralized control, the RIBMNW24B-BCAI relay accepts an analog input and can directly control equipment like unit heaters. With an onboard BACnet interface, the relay itself can help to provide basic controls, often eliminating the need for a separate DDC near the field device. It’s a smart way to reduce panel density and cabling complexity.
Dry-Contact Logic for Long Cable Runs
RIB01BDC
When controllers are far from load devices, or when you have to deal with voltage drop on long cable runs, dry-contact relays shine. The RIB01BDC uses simple contact closure for control, so you only have to pull two low-voltage wires, making it ideal for applications where running full coil voltage would be costly or impractical. It’s class-2 compatible, which may minimize conduit labor depending on your spec.
Classic Relays That Still Earn Their Place
RIBU1C-N4
The ubiquitous RIBU1C is a field staple for a reason—broad voltage tolerance, SPDT contacts, and pre-wired convenience make it a versatile all-purpose option. The -N4 version adds NEMA 4 rated housing, letting you deploy it outdoors or in wet industrial spaces without extra enclosures.
Other durable RIB relays, from single-pole to higher-capacity dual-pole versions, remain integral for simple control tasks, panel builds, and universal switching needs on the job.
Putting It All Together in 2026
In complex buildings where controllers, safety systems, and field devices must work together seamlessly, having the right RIB® products makes a real difference. Today’s systems are more integrated and networked than ever, and the right combination of logic relays, BACnet interface devices, and flexible sensing relays can significantly reduce wiring, panel space, and troubleshooting time.
Whether you’re responding to service calls, spec’ing a control panel, or solving a challenging retrofit, these RIB® devices give you the flexibility to tackle a wide variety of scenarios without reinventing your parts kit.
