The Latching Series from Functional Devices Inc. (RIB Relays) comes prepackaged in their own NEMA 1 plastic enclosure with a 1/2" mounting nipple, LED indicator and pre-wired for a money-saving installation that is easy and quick.

These relays are activated by pulse commands from a controller or momentary switch closure. The relay contacts are mechanically latched in the closed position and the load will remain on in the event of a control panel failure period. If power is completely lost the contacts will remain in their last state and the load will activate upon the return of normal power or emergency power.

When I first heard of RIB relays I was imagining a rib shaped relay that perhaps smelled like barbeque sauce, then again I like to think everything smells like bbq sauce. Well I know it's going to be hard to believe but that is not what a RIB relay is. In fact RIB actually stands for "Relay In a Box" (no it's not an SNL skit) and is the name of its manufacturer, RIB Relays (Functional Devices, Inc.)-  easy to remember!

These RIB relays are essentially the complete package in one piece, how convenient!  They are multi-voltage so you're not up a creek if you're at a job site that requires various voltages.  They also have multi-contact ratings which will reduce your amount of inventory needed. The RIB relay has multiple installation methods such as conduit and screw mounting, unlike it's cousin the ice cube relay that requires din rail to be mounted.
 

The Pilot Series from RIB contains relays that are rated at 10 or 15 Amps. They have been packaged to save the installer the time, trouble and expense of buying separate components (relay, LED indicator, socket, mounting rail, transient protection and housing) and assembling them on the job or at the shop.One of the most popular products from this line is the RIBU1C. This  versatile relay in a box and can be used for energizing motors like fan motors, water pumps and VFDs.  Self-enclosed relays, like the RIBU1C, can even be used outside if they are housed in a NEMA 4 or NEMA 4X rated enclosure, another bonus!

The Power Series from RIB contains relays that are rated at 20 to 30 Amps. An externally visible LED indicates the status of the coil of the relay. The override switch (Closed-Open-Auto) , available on certain models, is a true override switch located on the load side of the relay. Power Series relays are available in Enclosed, T, and Panel Style packaging.

Finally, the Latching Series is RIB's newest line of relays. These relays are prepackaged in their own NEMA 1 plastic enclosure with a 1/2″ mounting nipple, LED indicator and pre-wired for fast, simple and cost effective installations. Activate latching rib relays through pulse commands from a controller.The relay contacts are mechanically latched in the closed position. In the event of a control panel failure – the load remains on. If power is completely lost, the contacts remain in their last state. The load activates upon the return of normal power or emergency power.

So no fork and knife required but these RIB relays are still pretty darn cool!  Check them out at www.wolfautomation.com or give us a call at 800-345-2623 for further information!
