Technology Talk: Guide To Functional Devices RIB Relays
Did you know Functional Devices created six different series for their popular RIB relays, guaranteeing a relay for every application? In this guide, you will find what makes each of these series unique to help you get a better understanding for the RIB relays that are available at Tower!
The Pilot Series contains relays that are rated at 10 or 15 Amps. They have been packaged to save the installer time, trouble, and the expense of buying separate components. This series comes with the relay itself, an LED indicator, socket, mounting rail, transient protection, and the housing. The relay also saves the installer assembling time on the job or at the shop because it comes pre-packaged. Click here for the Pilot Series quick reference sheet.
The Power Series contains relays that are rated at 20 or 30 Amp. This series is packaged to save the installer time, trouble, and the expense of buying separate components. It comes with the relay itself, LED indicator, socket, mounting rail, transient protection, and housing which are all the components you will need for your job. This will save the installer time on assembling, cutting costs. Click here for the Power Series quick reference sheet.
The Latching Series comes with a prepackaged in a NEMA 1 plastic enclosure with a 1/2″ mounting nipple, LED indicator, and pre-wired allowing for a money-saving and easy installation. 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.

Low Input/Optoisolated Series
The Optoisolated Series of relays may be used when the controller does not have sufficient coil drive power available to energize a relay of the desired contact rating. The power to energize the relay can be brought to the relay on a separate pair of the wires along with the control output of the controller or can be a local power source near the relay.

Alarm (Polarized) Series
The Alarm RIB series is equivalent to the standard RIB series except for the coil which is polarized. Functional devices currently offer nine different alarm relays, most of which have a similar non-polarized counterpart. The “FA” in the model name stands for the Fire Alarm. These relays are designed for operation in systems that supervision from controllers and utilize end-of-line resistors. The relay can also be operated from A/C voltage (non-polarized) if desired.

Dry Contact Input Relays
The Dry Contact Input series offers all the advantages of the standard RIB line plus it can be activated by a wide range of dry-contacts such as thermostats, switches, other relays, solid-state switches, etc. The dry contact input RIB provides the low-voltage(class2) power needed to activate the relay(self-powered)- just close the dry-contact input. The power to energize the relay can be brought to the relay on a separate pair of wires along with the control output of the controller or can be a local power source near the relay. The relay contacts are isolated from the input power and the dry contact input, thus they can be wired to switch any other power-load or low-voltage load.
