RIB, Finder, Siemens, Idec (and more!) Relays

KMC rcc series pneumatic relay familyIf you can't find the relay you're looking for, chances are Boston Aircontrols (BAI) has it in stock as we carry a large selection of relays from top manufacturers, such as Functional Devices (RIB®), IDEC, Finder, Honeywell, Siemens, Johnson Controls, KMC, TAC Invensys, etc.

As a premier HVAC controls distributor, we've built a reputation of delivering superior customer service not only because we carry most relays that you'll need-such as control, power, solid state, and time-but also because we know about how to apply, wire, and troubleshoot them.

BAI is your Relay Resource

We carry the largest selection of relays in stock at our warehouse, and offer the convenience of walk-in service or the option of having us ship your relay products anywhere in the world.
HVAC Controls System, DDCFunctional Devices RIB relays come fully packaged to save the installer the time, trouble, and expense of buying separate components and assembling them on the job, and are available in Enclosed, T, and Panel style packaging.

  • Pilot series (10 to 15 Amp relays)

  • Power series (20 to 30 Amp relays)
Other RIB relays available include but are not limited to:
  • Dry Contact Relays — which offers all the advantages of the standard RIB line, plus being activated by a wide range of dry-contacts such as thermostats, switches, etc.

  • Open Protocol Field Devices — these relays can be used instead of a more expensive multi-output controller when a few more control points are needed, and a large controller is too much for the job.

Since many contractors are brand-loyal, we also offer other Ice Cube relay manufacturer options
like Idec and Finder.

Finder-56.32.8.240IDEC offers the following relay series, but is not limited to:

  • General Purpose Relays (Ice Cube type)

  • PCB Relays-ideal for appliance or electronic PCB manufacturing

  • Solid State Relays—with built in heat sink and AC load ratings up to 660V/90A.
Finder—manufacturers a series of relays of miniature, PCB and
ultra-slim relays to accommodate a variety of power ranges and applications.

We also offer pneumatic and electric relays from major control manufacturers such as Honeywell, Siemens, Johnson Controls, and TAC Invensys.

So whether it's an electric enclosure neededSiemens Pneumatic relay, HVAC supplies,heating,ventilation,air conditioning controls for a Power Series Relay from RIB or the new SmartRelay from IDEC, at Boston Aircontrols, we are certain you'll find all that your HVAC job requires to make your installation a success.
