Relays

Pilot Series - view quick reference

The Pilot Series 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.

Power Series - view quick reference

The Power Series contains relays that are rated at 20 or 30 Amp. 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.

Latching Series - view quick reference

The Latching Series 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.

Low Input/Optoisolated Series - view quick reference

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 wires along with the control output of the controller, or can be a local power source near the relay.

Alarm Series - view quick reference

The Alarm RIB series is equivalent to the standard RIB series except for the coil which is polarized. We are currently offering nine alarm relays, most of which have a similar non-polarized counterpart. The "FA" in the model name stands for Fire Alarm. These relays are designed for operation in systems that require 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 Series - view quick reference

The Dry Contact Input RIB 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 (Class 2) 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 (see specifications for contact ratings). One model can be used for many installations (model RIB21CDC can operate from any voltage from 120Vac - 277Vac; see specifications for the input power of other models).

Specialty Peripheral Devices - view quick reference

If we do not already build a devices with specifications or packaging configurations you require, we will be happy to quote and design one for you. Functional Devices, Inc. is actively involved in the development, manufacturing, and production of special peripheral devices. They are either variations of existing Functional Devices products or entirely unique devices. We will help provide you with a product to fit your specific needs. Please contact us so we may review your project and special requirements.
