Pilot Relays Series from Functional Devices

- View quick reference

 

The Pilot Series Relays are rated at 10 or 15 amps. Rather than buying separate components (relay, LED indicator, socket, mounting rail, transient protection, and housing) and assembling them on the job or at the shop, Pilot Series Relays are prepackaged to save the service professional time, trouble, and expense. A few popular Pilot Relays are RIBH1C, RIBU1C, RIBU1S, and RIB2401DView Pilot RIB Relays.

Power Series Relays, rated at 20 or 30 Amps, also come packaged to make the professional’s job easier. With these relays there is no need to buy separate components to assemble on the job. Some popular Power Series Relays on our site include RIB013Pand RIB2402B. View the complete list of Power Relays.

Latching Series

For fast and easy installations, FDI Latching RIB comes pre-wired and pre-packaged with its own NEMA 1 plastic enclosure with a 1/2 mounting nipple, and LED indicator. Pulse commands from a controller or momentary switch closure activate these RIB relays. In the event of a temporary control panel failure, the relay contacts are mechanically latched in the closed position and the load will remain on. In the event of a complete power failure, the contacts will remain in their last state, and the load will activate upon the return of normal power or emergency power. A popular Latching Relay from this series is RIBL12B. View More Latching Relays.

Low Input/Optoisolated Series

View quick reference 

Optoisolated relays are the answer to greater coil drive power. Not only are the power settings adjustable on these relays, but additional power can be boosted through a separate pair of wires or from a local nearby relay.  View Optoisolated Relays.

Polarized Series

What’s the difference between polarized RIB and non-polarized RIB?  

The Polarized RIB Series is distinguished from the standard RIB series only by its polarized coil; otherwise, they are identical. Polarized RIB Relays work in systems requiring supervision from controllers, utilizing EOLR (end-of-line resistors). These relays can optionally be used with (non-polarized) A/C voltage as well.

Dry Contact Input Series

The Dry Contact Input RIB Series offers versatility. Not only does it have all of the advantages of the standard RIB line, but these relays can be activated by a variety of dry-contacts such as thermostats, switches, other relays, solid-state switches, etc. When the dry-contact input is closed, the Dry Contact Input RIB provides the Class 2 low-voltage power required to activate the relay (self-powered).

This relay can optionally be powered through a separate pair of wires and the control output of the controller, or from a local power source. The relay contacts can be wired to switch another power-load or low-voltage load (see specifications for contact ratings) since input power and dry contact input is isolated from the relay contacts. These relays offer versatility. For example, model RIB21CDC can operate from a voltage ranging from 120Vac-277Vac, allowing these relays to be used for many installations. (Specifications for input power may vary with other models). View Dry Contact Relays.
